Answer:

Charles completed the quiz problems at the slowest rate

Step-by-step explanation:

we know that

To find out the unit rate divide the number of quiz problems by the time employed

1) Maya completed 15 quiz problems in 10 minutes

so

\frac{15}{10}=1.5\ quiz\ problems\ per\ minute

2) Andrew completed 12 quiz problems in 8 minutes

so

\frac{12}{8}=1.5\ quiz\ problems\ per\ minute

3) Charles completed 16 quiz problems in 16 minutes

so

\frac{16}{16}=1\ quiz\ problem\ per\ minute

Compare the unit rates

1 < 1.5

therefore

Charles completed the quiz problems at the slowest rate

What is the slope of the line that passes through (-2,7) and (4, 9)? Type a numerical answer in the space provided. If
lord [1]

Answer:

1/3

Step-by-step explanation:

You need to use slope formula. (the change in Y over the change in X = Slope [x1-x2/y1-y2 = slope]). I believe you can also use point slope formula, but I forgot how to do that one.

First, you would set up the equation.

7-9/-2-4 OR 9-7/4+2

you would then solve to get

-2/-6 OR 2/6

when simplified you get

1/3

for both. Hope it helps!
