So this equation is written in y=mx+b form where m is the slope, in this case -1, b is the y- intercept in this case 3. So to graph the y intercept is on the vertical line x=0 at 3. and the slope, or rate of change is -1. The line would go from the top left to the bottom right crossing through the point (0,3). Hope this helps.
Determined by the signs multiplication is × or using it or could be 2 numbers attached like this 2y but for deciding it's a ÷ or / but that is some of the signs
