Answer:
(See the third picture)
Explanation:
Start by turning everything to slope-intercept form:

Next, plot down the y-intercept on the graph (which in this case is -4):
(The y-intercept is the point where a line crosses the y-axis, thus, the y-intercept must be (0, y))
(See the first picture)
Next up, plot down the next point with the slope, recall that the graph is rise over run, or more specifically, y over x.
The slope is 7/3, the rise is 7 and the run is 3, so to draw the next point, start at your y-intercept, and go 7 units up, and 3 to the right, the next point should look like this:
(See the second picture)
And finally, draw a straight line across both points:
