What is the slope of the line that passes through the point (-5,-7) and (4,1)? Write your answer in simplest form

m =

Step-by-step explanation:

Slope = Change of y/Change of x

-7 - 1 = -8

-5 - 4 = -9

Slope = 8/9

a) what number, when added to negative four, is equal to negative five?

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
