Question

3. Which statements about graphed lines are true? Select all that apply.

A. A vertical line has an undefined slope.
B. The equation y = mx + b can be used to describe the relationship of a vertical
line.
C. A line represented by x = -8 is a function.
D. A horizontal line has a slope of zero.

Answer 1

A, D

Explanation:

b. mx+b can't describe the relationship of a vertical line since it's slope is undefined

c. x = -8 shows no relation to anything so it isn't a function

hopefully that works
