Exercise 31 Page 248

To graph the equation, we first have to rewrite the left-hand side and right-hand side as linear functions in slope-intercept form. Let's enter these equations in our calculator by pressing $\boxed{\text{Y}=}$ and then writing them on the first two rows.

When the equations have been entered we can plot them by pressing $\boxed{\text{GRAPH}}.$

To find the intersection point we can use the tool intersect, which we find by pressing $\boxed{2nd}$ and $\boxed{CALC}.$

Having selected intersect, we will see the graphs again. Now we have to choose the points between which we want to calculate the intersection point and make a best guess for the point of intersection. After that, the calculator will display the $x\text{-}$ and $y\text{-}$values of the intersection of the curves.
