A line has a slope of -2 and passes through the point (-2,8). Which is the equation of the line?
A. Y = -2x - 2
B. Y = -2x + 4
C. Y = -2x + 14
D. Y = 8x - 2

y=-2x+4

Step-by-step explanation:

y=mx+b

m is the slope so the equation looks like this:

y=-2x+b

Now we just need to find b or the y-intercept

so distribute -2 into x and 8 into y (x,y) (-2,8)

8=-2(-2)+b

Multiply -2 and -2 which is 4

8=4+b

Subtract by 4 on both sides:

b=4

So the equation is

y=-2x+4

Hope this helps!
