Determine the slope and y-intercept from the following equation.
Y=mx+b equation example. B 1 value of y when x0 So. Write an equation using Y MX B Form. The final equation is in the slope-intercept form y mxb y m x b.
With that equation you can now. Y 2x 1. B 7 4 b 7 4.
If m 0 then the equation y mx b becomes y b and is the equation of a horizontal line. Today she worked an 8 hour shift and was paid 9200. Write the slope-intercept form of the equation of each line.
A machine can make 5 miles of ribbon in an hour. Comparing the last two equations we get the y-intercept to be. Plot a graph of the amount Betsy earns against the time she works for.
0 m02 b 1 716 m719 b 2 Solve for m by multiplying equation 1 by -1 and adding to equation 2. 0 m-02 - b 716 m719 b. Since it lies on this line we also have.

For the equation y5x-6 you start with the constant. In this case the number. M 0 x y b m x y b mx y b y mx b Use the definition of slope.
Any equation in ymxb form is as easy as counting and connecting the dots. Y 32x 3. Y mx b 1 2 3 Slope y-intercept 4 y x.
Graph linear equations using ymxb If you like this video. Choose any value for x and find the matching value for y. Graph the length of the ribbon the.
Y mx b -2 eq1 - eq2 we get y - y mx - x then m y - yx - x. Get step-by-step solutions from expert tutors as fast as 15-30 minutes. ABpasses through x y and 0 b so that x2 x x1 0 y2 y and y1 b.
Y 5 On the same pair of axes graph the lines y 2 and y 3. For example if the slope of a line is 3 2 and its y-intercept is 14 an equation of the line is y 3 2 x 14. Equation in Y mx b form.
M 2 1 2. Linear Equations and y mx b Class Examples. Find the equation of a straight line whose x -intercept is a a and y -intercept is b b as shown in the following figure.
Y mx b m slope 2 b the y intercept 12 The slope intercept form of the equation. Check for yourself that x1 and y3 is actually on the line. Equation has the mx b form of.
Your first 5 questions are on us. Correct Reading mErroneous Reading b Write a pair of equations representing the two known points. Thats the number without the x.
6 rows If the slope m and y-intercept b are given then the equation of the straight line can be. Y 21 1 3. Betsy works as waitress.
For example when x is 1. Y mx b -1 Now take a particular point Px y on this line. Transforming an equation from standard form of a linear equation to slope-intercept form.
The standard form of this equation is 2x 3y 42. Y 2x 12.
