If you have a table that tells you the (x,y) or coordinates on a graph you can take those coordinates and insert them into the equation y=mx=b. this is the equation to find the slope of a line. If you solve for b in the equation you will have the y intercept. the mx would be the slope.
Answer:
(9,4)

4 : 5
300 : ?
Divide 300 by 4 to find out what '1 part' would count as:
300/4 = 75
Multiply this by 5
75 x 5 = 375
Add the two values together
375 + 300 = 675
There are 675 students

Ur points are set up as (x,y). The range is going to be all the y values.
So ur range is { 2,4,6}...if they repeat, u only have to write them once
Let n represent the number.
"the sum of a number and 7" is (n+7)
Three times "the sum of a number and 7" is 3(n+7)
"is" translates to "=".
"five times the number" is 5n
Two less than "five times the number" is 5n-2
Your equation is
3(n+7) = 5n-2
