(7, –3) and (6, –8)

Question

Express the equation in slope-intercept form.

Answer 1

Slope is rise over run or change in y values divided by change in x values

m=(-3 - -8)/(7-6) = (-3+8)/1 = 5

y+3 = 5(x-7) = 5x -35

y+3 = 5x-35

y= 5x -38 slope is 5, y intercept is -38

check the answer and plug in a point into the equatio

-3 = 5(7) -38 = 35-38 = -3

or plug in the other point

-8 = 5(6)-38 = 30-38 = -8

Equation in slope intercept form passing though those 2 points is y=5x-38
