Question

I need the answer to this please

Answer 1

y = - 2x - 18

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute (- 7, - 4) into the partial equation

- 4 = 14 + c ⇒ c = - 4 - 14 = - 18

y = - 2x - 18 ← equation of line
