Question

What is the equation of the line that passes through the points (2,-2) and (3,-4)

Answer 1

y + 2 = -2(x - 2) (point-slope form)

y = -2x + 2 (slope-intercept form)

2x + y = 2 (standard form)

Explanation:

`m = ( - 4 - ( - 2))/(3 - 2) = - (2)/(1) = - 2`

`y + 2 = - 2(x - 2)`

`y + 2 = - 2x + 4`

`y = - 2x + 2`

`2x + y = 2`
