Hello
Perpendicular means that the slope will be a negative reciprocal of the original.
Lets start with slope-intercept form
y = mx + b (m is slope and b is y-intercept).
The x axis has the equation of y=0. Thus the line perpendicular to this will be parallel to the x axis.
Thus will be in form of x = something.
Since we know our line passes through -5,3 --- we have the final equation of x = -5.
Hope this helps

Perpendicular to the x-axis means it's a vertical line, which also means it's parallel to the y-axis. If it passes through (-5,3), then the equation is x = -5.

the answer is x = -5 because perpendicular angles makes right angles and so you want it to go straight down through the x axis and since it needs to go through -5,3 you need the x to be -5 and it will go through all ys.
