Answer:
y = 7
Explanation:
x = - 5 is a vertical line parallel to the y- axis.
A perpendicular line to it will be a horizontal line parallel to the x- axis with equation
y = c
Where c is the value of the y- coordinates the line passes through.
The line passes through (2, 7) with y- coordinate of 7, thus
y = 7 ← equation of perpendicular line
