Question

Solving Systems of Equations Graphically

Answer 1

first, you have to graph your equations. You can do that tabulating
for y-2x=-1

for x+3y=4

The two Lines :

If you want The intersection of these lines you have to equate the equations
y=2x-1 and y=(4-x)/3
2x-1 = (4-x)/3
x=1
replacing in any equation you get y
y= 2(1)-1 = 1
the intersection is (1,1)
