How do you graph x-7?

Answer 1

x-7 can also be written as two different functions: y=x-7 and x=y+7

So, when x=0, y=-7. And, when y=0, x=7.

Since there is not any fractions in front of x in the function y=x-7, for every positive move one space on the x-axis, you would move one positive space on the y-axis. Conversely, for every negative move you make on the x-axis, you would move one negative move on the y-axis.

So mapping on a graph paper with x,y - axis would be like this for y=x-7:

-positive x-axis:

(0,-7), (1,-6), (2,-5), (3,-4), and so forth. Or: when x=0, y=-7, and when x=1, x=-6, and when x=2, y=-5, and when x=3, y=-4, and so forth.

On the negative x-axis, reverse the numbers and subtract by one:

(-1,-8), (-2,-9), (-3, -10), and so forth.
