Answer:
so, here we have a line that is perpendicular to a the line 1/4x -4and we are asked for the perpendicular line which passes through the point (-4,8)
Step-by-step explanation:
1. calculate perpendicular line (i.e. at 90 degrees to the line)
2. m1 x m2 = -1 where slope is m. and m1 = 1/4 (from the original equation)
1/4 x m2 = -1 , therefore m2 = -1/(1/4) = -1 x (4/1) = -4
3. therefore the equation is : y= -4x - 4
