Answer:
Slope of parallel: -1/4
Slope of perpendicular: 4
y=mx+b
m=slope
parallel= slope
perpendicular= slope opposite
1. Take the two x-axis intersections.
For Q 31 it is:
x = -4 and x = 0
2. Reorganise the previous equations
x +4 = 0 and x = 0
3. Put the x side in brackets
x(x+4)
4. Done
—-
Q 32
x = -1
x = 5
x + 1 = 0
x - 5 = 0
(x+1)(x-5)
