Find the slope and y-intercept

x=-9

a) slope:0;y-intercept: (0,-9)
b) slope: undefined; y-intercept:
(0,-9)
c) slope: 0;y-intercept:none
c) slope: undefined;y-intercept:none

could you tell me what YOU think the answer might be?

answer a

you got it

To find the slope and y-intercept given the equation x = -9, we need to rewrite the equation in the standard form y = mx + b, where m is the slope and b is the y-intercept.

However, the given equation x = -9 is a vertical line parallel to the y-axis. In this case, the slope is undefined because it represents a vertical line.

And since the line is parallel to the y-axis and does not intersect the y-axis, the y-intercept is also undefined.

Therefore, the correct answer is b) slope: undefined; y-intercept: (0,-9).
