Question

7x-3y=12
Need graphing or explaining how to do it bc I am confused.

Answer 1

(See the third picture)

Explanation:

Start by turning everything to slope-intercept form:

`7x-3y=12\\-3y=-7x+12\\y=(7)/(3)x-4`

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:

Answer 2

Take two points and connect them with a line.

Explanation:

We can take the points (0,-4) and (1,-
`(5)/(3)`). Now we can connect the two points with a line and we get our graph.
