Answer 4

C)The graph has a positive rate of change.

Answer 5

Okay now we calculate the slope of the graph
taking two points (0,0) and (1,30)

now slope becomes (30-0)/(1-0) = 30/1 = 30
now u know that slope is positive and is not zero options B and D ruled out!

and now if we manage to get an equation for this line
y = mx as it passes through the origin

and m = 30
so

y = 30x is the line where y is rental cost and x is thetime in days

as for bit A (The rental cost is $150 per day) lets see the rental cost per day

taking x as 1 day so

y = 30*1 = 30dollars not 150 dollars

so only c is true!
