Coordinate points are set up as (x, y) so...
x = 3
y = -3
Step 1: Plug 3 into x and -3 in to y in the equation: y = 4x - 1
-3 = 4(3) - 1
Step 2: Solve using basic order of operation
-3 = 12 - 1
-3 = 11
If the end result is equal to each other othen it is on the line y = 4x - 1. If not then the point isn't on the line
Hope this helped!

60 miles an hour for 45 minutes = 45 miles
50 miles per hour for 30 minutes = 25 miles
Total =70 miles
Answer:
Line A and Line C are parallel
Step-by-step explanation:
<u>Slope Equation: </u> 
<u>Step 1: Find the slope of the first line</u>
Line a passes through (-1, -2) and (1, 0).
<u>Step 2: Find the slope of the second line</u>
Line b passes through (4, 2) and (2, -2).
<u>Step 3: Find the slope of the third line.</u>
Line c passes through (0, 2) and (-1, 1).
Answer: Line A and Line C are parallel
Answer:
Two students will take 24 minutes to wash the car.
Step-by-step explanation:
In this case we can apply a rule of three to find out the time that will take for the students to wash the car. This has to be done such as:
3 students -> 16 minutes
2 students -> x minutes
3/2 = 16/x
But in this cases the problem states that this variables are inversely proportionate, which means that if there's less students washing the car they will take more time to finish the job. So we need to invert one of the fractions before computing the result.
3/2 = x/16
2*x = 3*16
x = 48/2 = 24 minutes.
Two students will take 24 minutes to wash the car.
