Question

What is an equation of the line that passes through the points (-2, -7) and (-1, -3)?

Answer 1

Answer:

y = 4x + 1

Step-by-step explanation:

Answer 2

Answer:

y = 4x + 1

Step-by-step explanation:

Find slope, rise over run

$\frac{y_{2}-y_{1} }{x_{2}-x_{1}} = \frac{-3--7}{-1--2} = \frac{4}{1} = 4$

find y intercept by plugging in one of the coordinates in  y=mx+b, including m=4

-7 = 4(-2) + b

1 = b
