Question

John began his job making $25 the first day. After that he was paid $6.75 per hour.Make a T-table for the equation for this, using the x-values: 0, 20, 40. Type in the ordered pairs you get as your answer, in this form: (0, number), (20, number), (40, number).

Answer 1

The y=mx+b is a pretty simple equation once you understand it. The Y is going to be the answer once the equation is solved. The X is the variable that changes. So for 2, the values are 0, 20 and 40. This means that they are looking or how much he made after 0, 20 and 40 hours. The number of days varies, thus this is the X variable. The B is the y-intercept, it's wherever the line touched the y-axis. This number never changes no matter how the m or x change. In this case, john made 25 the first day, it will never change, and so it is the B. The M is the slope, or how the line looks (negative or positive, and the steepness). The M in this problem is what the X is multiplied by, so in this problem, it is 6.75.

y=6.75x+25

Now for the next problem, you are asked to determine the values for 0, 20, and 40. In the (x,y) format, they are they X. If you plug the Xs into the formula above, then you will be solving for the Ys and be able to make the table.
