Answer:
3)
4) a)
b)
Step-by-step explanation:
<u>Exercise 3</u>
<u>Exercise 4</u>
a) If L2 is parallel to L1, it has the same slope (gradient) ⇒
If L2 passes through point (3, 1):
So L2 = L1
b) If L3 is perpendicular to L1, then the slope of L3 is the negative reciprocals of the slope of L1 ⇒
If L3 passes through point (-5, 2):
The 0.072 will be you're answer
He can shoot 6 because at this point we are diving 72 divided by 12 equals 6 hope it helps
20
20 = 1 x 20
100 = 5 x 20
