Answer:
that would be the number 3 because your moving 3 unit down which is subtracting 1 each time so u will be left with 3
X = number of hours traveled
Y = Total miles on the car
Y = 60x +45 000
for 13 hours
Y = 60(13) + 45 000
Y = 45 780
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):
