Please help i hate geometry

a) 4/5 b) -3/4

Step-by-step explanation:

lines that are parallel have the same gradient. So the gradient is 4/5

Lines that are perpendicular have "opposite reciprocal" gradient: flip the sign, then flip the numerator and denominator (top/bottom). So the gradient  is -3/4
