Step-by-step explanation:
Equation of the line perpendicular to x = -6 is y = -2
Step-by-step explanation:
The equation of a line in the slope-intercept force is
where
m is the slope
are the coordinates of a point on the line
In this problem, we have already a point on the line:
Concerning the slope, we are told that the line is perpendicular to the line
x = -6
This line is a vertical line: therefore, our line must be a horizontal line, so its slope is
So now we can find the equation of the line:
