What is the slope of the line that passes through the points (-5,2) and (-7,6)

-2

Step-by-step explanation:

remember slope is y2-y1/x2-x1

6-2/-7-(-5)

4/-2= -2

Find the gradient of the line.

Since Gradient = Rise / Run,

Gradient = (2-6) / (-5+7) = -4 / 2 = -2

Hence, the slope of the line is -2.

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.

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
