Write a point-slope form of an equation for a horizontal line that passes through (5, -9)

See below.

Step-by-step explanation:

Point-slope form is y - y1 = m(x - x1) where m = slope and (x1,y1) is a point on the line.

Because the line is horizontal the slope m = 0  so the answer is:-

y - (-9) = 0(x - 5)

or y + 9 = 0(x - 5)   which simplifies to:

y + 9 = 0

giving  y = -9.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

no one knows lol
