This is kinda hard to explain but I'll try my best. Here's a tip, the fractions that are on the ruler really mean 10,20,30,40,50,60,70,80,90, and 100. So, when you look at the decimals on number 7, you have to try to turn them into fractions in your head. For example, 0.9 is actually 9/10 or 90.
The line which represents the equation x = 5 is a vertical line that passes through any point hax x-coordinate of 5
Then the perpendicular line to this line must be a horizontal line
The equation of any horizontal line is y = b, where
b is the y-coordinate of any point that lies on the line
Since the line passes through the point (-2, 2), then
b = 2
Then the equation of the line is
y = 2
