Slopes Math Is Fun
The y-intercept of a line is the y-coordinate of the point of intersection between the graph of the line and the y-intercept. A graphical depiction is shown below.

The Gradient 4 2 2.
Slopes math is fun. Think about if you were like skateboarding and you were coming along and you hit this ramp. In differential calculus the slope of Slope Numerical measure of a lines inclination relative to the horizontal. If you pick two points on a line --- x1y1 and x2y2 --- you can calculate the slope by dividing y2 - y1 over x2 - x1.
The Gradient 3 3 1. Here are the formulas used to find the slope of a line. In analytic geometry the slope of any line ray or line segment is the ratio of the vertical to the horizontal distance between any two points on it slope equals rise over run.
Back in my school days we were told to simply memorize this fact of m. However in math slope is defined as you move from left to right. Types of slopes Positive slopes Negative slopes Zero slopes No slope These are the 4 types of slopes A no slope A no slope is when.
So the Gradient is equal to 1. Keeping this fact in mind by definition the slope is the measure of the steepness of a line. Here some pictures of slopes A positive slope Here is a no slope undefined slope A negative slope A zero slope Here is a random video Harlem shake.
And heres how you can tell. One point on the line. This is an uphill ramp.
For a vertical line m undefined. Slope Fields are a strange concept they look funny but they really arent that difficult. Why is this the case.
For a horizontal line m 0. The slope-intercept formula of a linear equation is y mx b where m represents the slope and b represents the y-intercept. Let m slope.
The slope formula uses two points x 1 y 1 and x 2 y 2 to calculate the change in y over the change in x. We write y fx on the curve since y is a function of x. The line is less steep and so the Gradient.
How steep a line is. In this example the slope is 35 06 Also called gradient. Why is this the case.
The steeper the hill the harder it is for you to keep yourself moving. Linear Equations Graphing Method 2 - Slope Intercept Form 2 - Cool Math has free online cool math lessons cool math games and fun math activities. The rise of a road between two points is the difference between the altitude of the road at those two points say y1 and y2 or in other words the rise is y2 y1 Δ y.
In real life we see slope in any direction. If a line is vertical the slope is undefined see below. This video screencast was created with Doceri on an iPad.
Doceri is free in the iTunes app store. Y y 1 m x x 1 The equation is useful when we know. Equations for Slope The slope is defined as the change in y over the change in x of a line.
Have a play drag. Slope is a ratio that includes how y changes for every unit increase of x. Anytime youre given a graph theres my axis and heres my line.
In mind with slope and that is sometimes slopes are positive numbers and sometimes slopes are negative numbers. M and want to find other points on the line. If a line is horizontal the slope is zero.
The line is steeper and so the Gradient is larger. Slope fields are little lines on a coordinate system graph that represent the slope for that xy combination for a particular differential equation remember that a differential equation represents a slope. This is a constant function.
X1y1 and the slope of the line. The slope is the rise the vertical change over the run the horizontal change. The Gradient 3 5 06.
The slope formula is the vertical change in y divided by the horizontal change in x sometimes called rise over run. That is as x varies y varies also. Most textbooks do not give a clear reason for an undefined and zero slope.
Illustrated definition of Slope. Really clear math lessons pre-algebra algebra precalculus cool math games online graphing calculators geometry art fractals polyhedra parents and teachers areas too. We call that a positive slope.
We need to find this slope to solve many applications since it tells us the rate of change at a particular instant. The slope of a curve y fx at the point P means the slope of the tangent at the point P.
