Question

Use slopes to determine whether the lines AB and CD are parallel, perpendicular, or neither. SHOW WORK

A(-10, 8) and B (-9,4).
C (-5, 12) and D (2,9).

Answer 1

Answer: The lines will be neither

Line A is Purple dot

Line B is Blue dot

Line C is Red dot

Line D is Green dot

Answer 2

Neither

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
