Step-by-step explanation:

Dilation changes the distance to the center of dilation by a factor equal to the scale factor.

Part A:

Point R is 2 grid squares left and 6 grid squares down from the center of dilation at (3, 7). So, point R' will be (3/2)(2) = 3 grid squares left and (3/2)(6) = 9 grid squares down from that center.

Likewise, point T is 2 square diagonals down and right of (3, 7), so T' will be 1 more square diagonal farther.

Part B:

As in Part A, the scale factor multiplies the distance from the center of dilation. L will be the midpoint between R and (-1, 9); M will be the midpoint between T and (-1, 9).

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
