Answer:
The speeds are equal.
Step-by-step explanation:
<em>100 meters in 9.75 seconds</em> compared to <em>200 meters in 19.5 seconds</em>.
(100 m)/(9.75 s) = 10.2564 m/s
(200 m)/(19.5 s) = 10.2564 m/s
The speeds are equal.
Answer:
x=7 y=0 this is the answer
Equation in point-slope form is 
Option C is correct.
Step-by-step explanation:
We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5
The formula used for point-slope form is:

We are given slope m = 4/5
Point (-7,9) where x₁ = -7 and y₁ = 9
Putting values in the formula:

So, equation in point-slope form is 
Option C is correct.

In this question, you're trying to find the unit rate in which the teacher can grade tests.
A unit rate is another word for "rate of change".
This means that we have to find how many tests the teacher could grade in 1 minute.
To find the unit rate, divide 18 by 15
18 ÷ 15 = 1.2
This means that Mr. Rivera can grade 1.2 tests in 1 minute.
Answer:
1.2 tests
