Question

Which equation graphs as a vertical line with an undefined slope?

A) y = 3x
B) x = 2/3
C) y = 2/3
D) y = −2/3 x + 1

Answer 1

c y=2/3 . the number in front of x is the slope and the number that is added or subtracted at the end is the y coordinate

Answer 2

Explanation:

The equation is

x = 2/3

Explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = y intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

From the information given,

Slope, m is undefined.

This means that the slope, m = 0

We won't represent it with the normal slope-intercept equation since the line is vertical with an undefined slope. It means that a straight vertical passes through the horizontal axis

The equation is will be

x = 2/3
