Which form of equation models the data if a is a negative integer and b is a positive integer? A. b = a x/y
B. y = ab^x
C. y = ax + b
D. y = ab^−x

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
