Question

Passes through
(1.2) and (3, -8).

with y=mx+b

Answer 1

y = -5x - 10

Explanation:

-8-2 -10

____ = ___ = -5

3 - 1 2

Answer 2

• y = -5x + 7

Explanation:

Find the slope:

• m = (- 8 - 2) / (3 - 1) = -10 / 2 = -5

Use the point (1, 2) and find the equation:

• y - 2 = -5(x - 1)
• y = -5x + 5 + 2
• y = -5x + 7
