Question 824044
The two straight lines y=3x+1 and y=-2x+16 and the curve {{{y=x^2+x-a}}}, where a is a
constant, all meet at the same point. Find the value of a and then, for that value of a, plot the
curve {{{y=x^2+x-a}}}.
--------------------
Find the intersection of the 2 lines.
Solve for a.
Plot the curve.
