(a) The gradient is \frac{40}{5}=\boxed{8}, and represents the cost of buying one book in dollars.

(b) Draw the line through (0,0) and (20, 130).

(c) Since the gradient of the line representing company B is less (6.5 vs 8), it is better to buy books from company B because they are cheaper.

What’s the correct answer for this question?
erma4kov [3.2K]

Answer:

A.

Step-by-step explanation:

Perpendicular => so it will have a slope of negative reciprocal to this slope

Slope = 2/3

Now

Point = (x,y) = (6,5)

So,

x = 6, y = 5

Substituting in the slope intercept form

5 = (2/3)(6)+b

5 = 4+b

=> b = 1

So, we have

m = 2/3

b = 1

Putting in the slope intercept equation

y = 2/3x+1
