Question

Write an equation in slope-intercept form of the line that passes through (6,

-1) and (3,
-7).

Answer 1

Answer: y = 2x - 13

Explanation:

y=mx + b

`m= (-7-(-1))/(3-6)`

`= (-6)/(-3)`

`m = 2`

y = 2x + b

(6, -1) <-- use to find "b" by substituting either one of the coordinates

-1 = 2(6) + b

-1 = 12 + b

-13 = b

y = 2x - 13
