Question

The slope of the line is -3. Use the coordinates of the labeled point to find the point-slope equation of the line.

Answer 1

Use the point-slope formula for a line:

y-(-7) = -3(x-5) (answer)

Review: the eq'n of a str line with slope m and one given point (h,k) is

y-k = m(x-h).

Answer 2

`m = (Y_2 - Y_1)/(X_2-X_1)`


`-3 = (y + 7)/(x - 5)`


`y + 7= -3(x - 5)`
