Ruby and her children went into a bakery and she bought $18 worth of donuts and cookies. Each donut costs $1 and each cookie costs $1.50. She bought a total of 15
donuts and cookies altogether. Graphically solve a system of equations in order to
determine the number of donuts, 2, and the number of cookies, y, that Ruby bought.

I did this minutes ago but I forgot to mention this could anyone do the work in a graph like plot each line and everything thanks. Ignore the last one.
