#### Answer

The graph is shown below:

#### Work Step by Step

Equation: y=-5x+12 The general form of a linear equation is y=mx+b where m is the slope and b is the y-intercept. In the equation above the y-intercept, b, is +12 so start by plotting the point (0,12). In the equation above the slope, m, is -5 and since slope= $\frac{rise}{run}$ you go down 5 units and to the right one unit from each point starting from the y-intercept to get the final graph.
