Ellen thinks that if a line has no slope, then it never touches the y-axis. which line proves that her statement is incorrect?
x=0
y=0
x=1
y=1

Step-by-step explanation:

If we graphed y=1, then it would be a horizontal line where a point would be on (0,1).

A horizontal line has no slope, and the y-intercept for y=1 is one.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
