Question

Write an equation of the line (-8, -5) (-3, 10)

Answer 1

Answer:

y = 3x + 19

Step-by-step explanation:

1) Compute the slope (Slope = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$)

   m = $\frac{10 - (-5)}{-3-(-8)}$

2) Refine

   m = 3

3) Plug the slope (3) into y = mx + b

   y = 3x + b

4) Plug in (-8,-5), x = -8, y = -5

   -5 = 3(-8) + b

5) Isolate b

   b = 19

6) Construct the line equation y = mx + b

    y = 3x + 19
