I can't help you with the graph, but the equations you need are:
y=x+5 and
y=12-4x/3
This comes from: # brownies = #donuts + 5
.75 * # brownies + # donuts = $9

asked 11/01/22Brianna and her children went into a bakery and she bought $9 worth of donuts and brownies. Each donut costs $1 and each brownie costs $0.75. She bought 5 more brownies than donuts. Graphically solve a system of equations in order to determine the number of donuts, x, and the number of brownies, y, that Brianna bought.
