So if you want to fit the y-intercepts or "b", on the y-axis you should go by 25's [0, 25, 50, 75, 100...]
If the x-axis <u>does not have to</u> follow the same pattern (25's), you should go by 5's [0, 5, 10, 15, 20...]
y = 7x + 50
y = 2x + 175
First I would plot the y-intercepts for each equation, then plot a few points with x = 5, 10, 15 Then draw a straight line.
The point where the two lines meet/cross paths is your solution. It should be (25, 225) The x-axis is the number of miles, and the y-axis is the total cost. So Truck driver A and B would arrive/be at the same place/meet in 25 miles at the same cost of $225

First, find the amount the sale is worth. To do such a thing, calculate 20% of 35$ like this
(35 * 20) / 100 = ?
To find the cost of 1 jean, take the sale's worth off the full price.
35 - ? = $
Then, multiply it by 6, for 6 jeans.
$ * 6 =
