Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2

ANSWER

or

EXPLANATION

For

We make y the subject to obtain,

We can easily graph this function, because we just have to transform the graph of by shifting the intercept up to .

As for the straight line, ,

We find the intercepts as follows,

When .

When .

We plot the points and

.

We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be
