Question

A line passes through the point (4,-4) and has a slope of -4. Find

the equation of the line.
O A. y = 40 + 20
ОВ.
y = -40 + 12
OC.
y = 40 + 12
OD.
y = -43 + 20



PLEASE SOMEONE ANSWER ASAP

Answer 1

y = - 4x + 12

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 = - 4 , then

y = - 4x + c ← is the partial equation

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

- 4 = - 16 + c ⇒ c = - 4 + 16 = 12

y = - 4x + 12 ← equation of line
