I think it 2 because did on paper
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180 degrees.
<ADB + <BDC = 180°
IT'S seen that BOTH ADB and BDC are 90 degrees
90+90= 180
You just subtract the x's and subtract the y's. So it will be 3- -2 and -1 - -5. Subtracting a negative is like adding a positive so your answer will be 5/4.
Answer: M (slope) = -1 / -3 = 0.3
