Question

(-3,6) (-2,9) write the equation in slope intercept form

Answer 1

y = 3x + 15


The rate of change is 3 which you can find using rise over run or a different method. If you have a graph you can see where the two lines intersect (connect or touch each other) to find your y (initial value).

Answer 2

y = 3x + 15

Explanation:

The slope-intercept form is y = mx + b

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Points (-3,6) (-2,9)

We see the y increase by 3 and the x increase by 1, so the slope is

m = 3

Y-intercept is located at (0,15)

So, the equation is y = 3x + 15
