I think the correct answer is D
Sqrt(x^2) = sqrt(20)
x = +2sqrt(5)
x = -2sqrt(5)
x1 = (- 0 + sqrt(0^2 - 4*1*(-20))) / (2*1)
X2 = (-0 - sqrt(0^2 - 4*1*(-20))) / (2*1)
Answer:
m = 3/5
Step-by-step explanation:
Slope Formula: 
Step 1: Find 2 coordinates
(0, 80)
(-50, 50)
Step 2: Find slope <em>m</em>
m = (50 - 80)/(-50 - 0)
m = -30/-50
m = 3/5
