Find the slope between the pair of points using the slope formula. (4,−5) and (0,−13)

jeka57 [31]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have (4, -5) and (0, -13).

Substitute:

$m=\dfrac{-13-(-5)}{0-4}=\dfrac{-13+5}{-4}=\dfrac{-8}{-4}=2$

Answer:

more than 410

Step-by-step explanation:

For x miles, the second plan costs ...

p2 = 50 +0.25(x -250)

For the first plan to be cheaper requires ...

p1 < p2

90 < 50 +0.25(x -250)

40 < 0.25(x -250) . . . . . . subtract 50

160 < x -250 . . . . . . . divide by 0.25

410 < x . . . . . . . . . add 250

For more than 410 miles in one day, the unlimited plan would save money.
