Answer:

See attached

Explanation:

You want the graph of y = -12x -3 plotted using the x- and y-intercepts.

Intercepts

The intercept form of the equation of a line is ...

x/a +y/b = 1

where 'a' is the x-intercept, and 'b' is the y-intercept.

Rearranging the given equation to this form, we get ...

12x +y = -3

x/(-3/12) +y/(-3) = 1 . . . . divide by -3

x/(-1/4) +y/(-3) = 1 . . . . . reduce the fraction

The x-intercept is -1/4, point (-1/4, 0).

The y-intercept is -3, point (0, -3).

The attached graph shows these points plotted and the line through them.
