Question

Write and equation in point slope form for the line through the given point with the given slope (10,-9);m=-2

Answer 1

y+9 = -2(x-10)

Explanation:

The equation for the slope is y2-y1 = m(x2-x1).

Notice that y1 is -9 and x1 is 10.

So the equation for the slope must be :

y-(-9) = -2(x-10) => y+9 = -2(x-10)
