What is the equation of the line that passes through the point (-2,7) and has a slope of -2

Let's say that y=mx+b, m=slope, b=y-intercept

y=-2x+b

We can solve for b using given coordinates on the line (-2,7)

7=-6*(-2)+b

b=-5

Therefore, the equation would be y=-2x-5.

Hope this helped!

Actually, the equation would be y = -2x + 3.
