You can put this solution on YOUR website!
The given equation is a line and you are asked to plot it on the closed interval from -4 to 10. So, plot the points where the x value is -4 and 10.
Plug in x = -4 and solve for y. Plot that point. (-4, -1)
Plug in x = 10 and solve for y. Plot that point too. (10, 27)
Now draw the line segment that has those two end points.
