Question

What is the equation of the line that passes through the point (-2,0) and has a slople of -2 ​

Answer 1

y= -2x-4

Explanation:

`(-2,0) = (x_1,y_1) \\ m = - 2`

Substitute values into point slope form

`y - y_1 = m(x - x_1) \\ y - 0 = - 2(x - ( - 2)) \\ y - 0 = - 2(x + 2) \\ y - 0 = - 2x - 4`

`y = - 2x - 4 + 0 \\ y= - 2x - 4`
