Take 1/2 of liear coefient, and square it
-18/2=-9, (-9)^2=81
add 81
factors to (y-9)²
In the figure,ABC is congruent to ADC . If the square ABCD is dilated by a factor of 2 to form A'B'C'D', the ratio of the area of A'B'C'D' to the area of ABCD is 1/2. Since the dilation is by a factor of 2, so the area of the A'B'C'D' should be smaller than the area of ABCD.

Quick maths
Step-by-step explanation:
take the two points let's say it's (1,5) and (2,6)
subtract, 6-5/2-1 = 1/1 = 1
the slope is 1
