Jackie And Bonnie Are Disagreeing On What Points The Two Graphs Below Intersect., Y= X^2-8x+15, Y=3x-13, Jackie States That The Graphs Intersects At (

Jackie and Bonnie are disagreeing on what points the two graphs below intersect.

y= x^2-8x+15
y=3x-13
Jackie states that the graphs intersects at (7, 0) and (4, 0). Bonnie however states that Jackie is not correct.
If you were Bonnie, how would you explain to Jackie her mistake?

 

The graphs intersect at (7,8) and (4,-1).

Although Jackies values for the x-coordinates are true, she did not substitute them to either of the two equations of the line to get the value of y and wrote 0 for the y-coordinates instead, which made her answer wrong.
