I put in a screenshot on what the graph would look like (i used desmos)
Step-by-step explanation:
Ok, you have the equation y=3-4x. This can be broken down into the y=mx+b format. -4 would be the m, and since m is the slope -4 would be the slope of your line. 3 would be your b- your y-intercept. Basically at (0,3) your line crosses the y-axis.
