Answer:

Neither

Step-by-step explanation:

Slope for AB is -4

Slope for CD is -3/7

in order to find the slope use this formula attached

AB -9-(-10) / 4-8 = -4         your y2 is 4 your y1 is 8 / x2 is -9 x1 is -10

CD 9-12 / 2-(-5)                 your y2 is 9 your y1 is 12 / x2 is 2  x1 is -5
