How do you graph #y=x+7# by plotting points?

The number in front of the #x# is the gradient, in this case it is 1. The #+7# is the y-axis intercept, so the line touches the y-axis at the coordinate #(0,7)#. So that's one point taken care of.

Plot at least two more points using the gradient (in this case 1).

Gradient = change in #y#/change in #x#

If the gradient = 1, that means that for every 1 you go in the y direction, you also go 1 in the x direction.

Using this, you can plot at least 2 more points, and then connect the points and extend the line.
