On the same coordinate plane make a line (x,y) that satisfy the rule
y= -3x-x
There seems to be an error in the equation given. It is y= -3x-x which simplifies to y= -4x. To make a line that satisfies this equation, you can choose any two points and plot them. One possible set of points could be (0,0) and (1,-4).
To plot the points, you start at the origin (0,0) and move one unit to the right along the x-axis to reach the point (1,0). From there, you move four units down to reach the point (1,-4), which lies on the line y = -4x. The resulting line passing through those two points would look like this:
graph{y=-4x [-10, 10, -5, 5]}
