The equation is:


y=21x

To graph that equation, as it is a equation for a line, you need to find the coordinates (x,y) for two points on the line.

To find a point on the line you give for one of the variables a value and calculate the value of the other variable with the equation.

If x= 5


\begin{gathered} y=21(5) \\ y=105 \end{gathered}

Then, when x=5 y=105. The first point have coordinates (5, 105)

If y= 0


\begin{gathered} 0=21x \\ (0)/(21)=x \\ x=0 \end{gathered}

Then, when y=0 x=0. The second point have coordinates (0, 0)

You put that points in the plane:

Draw a line that passes through taht points:
