Answer:
1. Kayla - the slope is undefined
2. Slope = [tex]\frac{1}{-2}[/tex] or -0.5
3. Slope = [tex]\frac{3}{2}[/tex] or 1.5
4. C
Step-by-step explanation:
A vertical line has undefined slope because all points on the line have the same x-coordinate
(0,1) (2,0)
[tex]\frac{1 - 0}{0 - 2}[/tex] = [tex]\frac{1}{-2}[/tex] = -0.5
(0,0) (4,6)
[tex]\frac{6 - 0}{4 - 0}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex] = 1.5
y = 1.5x
30 = 1.5(20)
30 = 30
