If a line's slope is

, the slope of the perpendicular line is

in this case, the given line has a slope 4, which is 4/1, so the perpendicular line has a slope/gradient
Round all of the numbers to the nearest 10 then solve the problem like normal
Its C! Hope this helps and can you mark me as brainliest :))
