The answer for number two

Answer:
A.
Step-by-step explanation:
m = y2-y1/x2-x1
m = 12-4/15-5
m = 8/10
m = 4/5
Slope formula:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
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)
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{8.0-4.0}{10-5}[/tex]
[tex]m=\frac{4.0}{5}[/tex]
Your answer is A
