Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
The discount was 25% off use 21/28 which is 75 percent of what it was before. 25 percent off.
Answer:
and
do not lie on the line
Step-by-step explanation:
Given

Required
Determine which points that are not on the line
First, we need to determine the slope (m) of the line:

Where


So;



Next, we determine the line equation using:

Where


becomes


To determine which point is on the line, we simply plug in the values of x to in the equation check.
For 
and 
Substitute 4 for x and 2 for y in 



<em>This point is on the graph</em>

For 
and
Substitute 4 for x and 3 for y in 



<em>This point is not on the graph</em>

For 
and 
Substitute 7 for x and 2 for y in
