Take a vertical line and place it on thegraph<span>. </span>If<span> the </span>graph is a function<span>, then no matter where on the </span>graph<span> you place the vertical line, the </span>graph<span>should only cross the vertical line once.</span>
Lets make the graph of our systems of equations:
The blue line correspond to the equation x-y=3 and the red one correspond to 7x-y=-3. The lines intersect at point (-1,-4), then, the solution of the system is (-1,-4).
=(9(1/3))^2+2+4/7
=(3^2)+2+4/7
=(9)+2+4/7
=11+4/7
=81/7
Step-by-step explanation:
