Question

What is the equation of the line graphed below? Write your answer in slope-intercept form. (y = mx + b)

Don't forget to simply if you can!

Answer 1

y = 2x + 2

Explanation:

Slope = (change in y-values)/(change in x-values)

Slope = (-6 - 6)/(-4 - 2)

Slope = -12/-6

Slope = 2

Use the slope = 2 and point (2, 6) and substitute into y = mx + b to solve for b.

y = mx + b

6 = 2(2) + b

6 = 4 + b

b = 2

The equation is y = 2x + 2

Answer 2

Y=-2x+10 is the equation
