Question

Which of the following is an equation of the line through (2, 3) and (-1, -12)?

Answer 1

y = 5x - 7

Explanation:

First point coordinates

x₁

2

y₁

3

Second point coordinates

x₂

-1

y₂

-12

Result

Slope (m)

5

m = -15 / -3 = -5 / -1 = 5

Your function

The entered points belong to an increasing, linear function.

Equation: y = 5x - 7.

Hope i helped :)
