Hi there!
To find the perpendicular slope you need to flip the fraction and change the sign. So 1/2=2/1 and tge original slope was positive, so the slope is -2. Now you sub in the point (-7,-4) in for x and y in the formula y=mx+b and solve for b (sub in 2 for m as well)
Y=mx+b
-4=-2*-7+b
-4=14+b
-4-14=b
B=-18
The equation is y=-2x-18
Hope this helps!
4.888...%
428 + 22 = 450
22/450 = 0.4888...
0.4888... x 100 = 4.888...
(dots mean the decimal goes on forever)
6 and 8 I believe is the answer
