# 1 Answer

passing through (-10, -4) and (-1, 2)

calculate slope of line:

(y

_{2 }- y_{1})/(x_{2 }- x_{1})[2 - (-4)]/[-1 - (-10)] ---> 6/9 ---> 2/3

so slope is 2/3.

we use the formula y = mx + b to calculate y intercept. Let's use first point to figure out b.

-4 = (2/3)(-10) + b

-4 = -20/3 + b

-4 + 20/3 = b

-12/3 + 20/3 = b

b = 8/3

**y-intercept is (0, 8/3)**
