Answer:

y + 8 = -4(x - 2)

Explanation:

Point-slope form of an equation is a fill-in-the-blank, shortcut way to write an equation of a line. This is the format:

y - Y = m(x - X)

You just fill in the slope for m and fill in the point for the X,Y.

Just leave the first y; it stays a y and the first x in the parenthesis stays as an x. You just have to be careful with your minus and negative signs.

Slope is given as -4 so fill that in for m.

and put (2,-8) in place of the X and Y.

y - Y = m(x - X)

y - -8 = -4(x - 2)

y + 8 = -4(x - 2)

Done! Hope this helps!
