Find the slope of a line that passes through the points (-1, -3) and (2, -2).

Step-by-step explanation:

(-2 + 3)/(2 + 1) = 1/3 is the slope

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
