Question

Write an equation of the line passing through the points (3.10) and (-1,-14)

Answer 1

y = 6x - 8

Explanation:

1) Compute the slope

`(-14-10)/(-1-3)`

2) Refine

m = 6

3) Plug the slope (6) into y = mx + b

y = 6x + b

4) Plug in (3,10)

10 = 6(3) + b

5) Isolate b

b = -8

6) Construct the line equation y = mx + b

y = 6x - 8
