Answer:
x = 4
Step-by-step explanation:
perpendicular lines have opposite and reciprocal slopes
the line y = 2 is a horizontal line, which means the slope is zero
also, y = 2 intersects the y-axis at 2
a line perpendicular to a horizontal line is a vertical line and, if it passes through the point (4,5) will intersect the x-axis at 4
therefore, the equation would be x = 4
