The graph of the following system of equations

2x + y = 6
6x + 3y = 18

a) overlapping lines
b) parallel lines
c) intersecting lines

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
