Answer:
THE GRAPH IS ATTACHED.
Step-by-step explanation:
The Slope-Intercept form of the equation of a line is:

Where "m" is the slope of the line and "b" is the y-intercept.
In this case, you have the first equation:

You can identify that:

If you convert the Mixed number to a Decimal number, you get:

Then, knowing the slope and the y-intercept, you can graph the line.
The second equation is:

Solve for "y":

Knowing that:

You can graph the line.
The point of intersection between both lines, is the solution of the system. This is:
Observe the graph attached.
Answer:
Peter walks at a rate of 13/4 miles per hour.
Step-by-step explanation:
Peter walks at a rate of 13/4 miles per hour because every hour, <em>represented by x</em>, he walks 3.25 hours or 13/4. y is the total miles he walked so if he walks two hours the y would equal 6.5 or 26/4 and the x would equal 2.
The sales tax is 3.49 I think
.38, .37, and .36 are all less than 1
The solutions are basically the points on the graph that the line passes through. The best way to pick them is to use the whole numbers that are on the corners of the little boxes instead of the middle.
(4, -5)
(3, -3)
(1, 1)
(0, 3)
(-1, 5)
and so on.
