graph{-3/7x - 1/7 [-10, 10, -5, 5]}

Explanation:

In this equation the -1/7−17 is the yy-intercept. since when x = 0x=0 y = 1/7y=17, so plot a point at (0,1/7)(0,17).

The coefficient of xx is the gradient / slope of the line, in this case the gradient is -3/7−37, to plot a second point on the graph move along the xx-axis by 33 then go along the yy-axis by -7−7, the negative means go down on the yy-axis. So plot a point at (3,-7)(3,−7).

Now that we have a point at (0,1/7)(0,17) and (3,-7)(3,−7), connect the points drawing a straight line.
