Question

The answer for number two

Answer 1

Answer:

A.

Step-by-step explanation:

m = y2-y1/x2-x1

m = 12-4/15-5

m = 8/10

m = 4/5

Answer 2

Slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

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)

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{8.0-4.0}{10-5}$

$m=\frac{4.0}{5}$

Your answer is A
