Question

The answer for number two

Answer 1

Slope formula:

`m=(y_(2)-y_(1))/(x_(2)-x_(1))`

Find 2 points to plug into this equation.

Let U.S. dollar be the x values

Let British pound by the y values

I will use the points(x,y):

(5, 4.0) and (10, 8.0)

(5, 4.0) = (x₁ , y₁)

(10, 8.0) = (x₂ , y₂)

`m=(y_(2)-y_(1))/(x_(2)-x_(1))`

`m=(8.0-4.0)/(10-5)`

`m=(4.0)/(5)`

Your answer is A

Answer 2

A.

Explanation:

m = y2-y1/x2-x1

m = 12-4/15-5

m = 8/10

m = 4/5
