Answer:

Solutions are (3,1) and (4,2)

Explanation:

Graph is shown in the attached sheet

Given are two systems of equations and we have to solve them using graph

For graphing let us first prepare table for x and y.

1)
y=(-2x)/(3) +3:\\y=2x-5

I line II line

x 0 4.5 3 x 0 2.5 3

y 3 0 1 y -5 0 1

The two lines intersect at (3,1)

Hence solution is (3,1)

--------------------------------------------

2)
y=(x)/(2) \\-6x+3y=-18

I line II line

x 0 2 4 x 0 6 4

y 0 1 2 y 3 0 2

The two lines intersect at (4,2)

Hence solution is (4,2)
