What happens when you have a negative coefficient in the formula, such as -3/4 in Y + 1 = -3/4(X - 8)?

• It inverts the X values

• It decreases the slope

• It increases the slope

• It makes the slope negative

What is the correct simplification of Y + 1 = -3/4(X + 8)?

• Y = -3/4X - 8

• Y = -3/4X - 5

• Y = -3/4X - 6

• Y = -3/4X - 7
