Hi Samantha!

To graph relations and inverse functions you may select ANY values for x (unless it results in a 0 in the denominator of a fraction) and plug them into your equation to find the corresponding y values. This will give you ordered pairs that can be graphed.

For example, if y=3-7x, then when x=0, y=3-7(0)=3-0=3. So (0,3) is a point on the graph. When x=2, y=3-7(2)=3-14=-11. So, (2,-11) is a point on the graph. And when x=-10, y=3-7(10)=3-70=-67. So, (-10,-67) is a point on the graph.

Graph the points and connect them to make a sketch of the graph.

I hope this helps!

Best regards!

Hi Samantha,

You have quite a bit of freedom.

You can pick values that do not make the denominator of a fraction 0.

Often people will pick numbers near 0 like -2,-1,0,1,2 , but it is up to you.

Let me know if this helpful.

Best regards?
