Find the slope, if it exists
x=-7
x=-7 is a vertical line parallel to the y axis.
The line is at x = -7.
To find the slope, we need to have a geometric figure or an equation involving two variables. However, the equation you provided, x = -7, represents a vertical line.
A vertical line does not have a slope because it is parallel to the y-axis and goes up and down infinitely. Slope is a measure of the steepness of a line, but for a vertical line, the steepness is undefined.
Therefore, the slope does not exist for the equation x = -7.
