Question

Solve the system of equations by graphing? x+y=3, y=2x-15

Answer 1

for x+y=3
if x=0 then y=3, we get x-intercept (0,3)
if y=0 then x=3, we get y-intercept (3,0)

so, the graph for system x+y=3 can represented bellow :

Answer 2

now, can u graph for the 2nd system ?

Answer 3

I can try
