Hi everyone..I have a question which was troubling me somwhow..

when I try to sketch the functions on a graph, I keep on getting lines which don't cut each other..

this is the question:

On a graph, plot the line y = 80 + 10x and y = 34x – x2. Mark clearly the y-intercept, x-intercepts, x-axis and y-axis.

Find the values of x where the two curves intersect.

Appreciate your responses...
