Answer:

The equation of this line is y = -2x + 3

Step-by-step explanation:

In order to find this, start with the basic form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the point in for (x1, y1)

y - 5 = -2(x + 1)

Now solve the equation for y.

y - 5 = -2x - 2

y = -2x + 3
