Question:ok i need some help with graphing these all help is appreciated and i am asking 2 per question so if you answer all of my questions and are helpful that is some serious points!it will be 3 questions and if you are helpful i will pick you all three times :) thanks in advance! it is home school and no friends or family can help either.
graph
1.3x+y=5
-2x+3y=4

2.2x=y+1
2x-y=5

thank you so much! please show work and give points :) 5 stars and best answer.

First, express each equation as y=

1.3x + y = 5 , subtract 1.3x from both sides and get
y = 5 - 1.3x

next, set X=0, so the first "point" is y=5 when x=0. Plot that point

Next, try x=10. In this case y= 5 - 13 or -8, so plot the point X=10, Y=-8. Now draw a line between the points You have plotted that equation.

---------

-2x + 3y = 4 , rearrange it so the y stuff is on the left
3y = 4 + 2x (simply add 2x to both sides)
Now divide both sides by 3 to get
y = (4 + 2x) / 3

Like above, set x=0 to get y = 4/3 or y=1.5
now set x=10 to get y = (4 + 20) / 3 = 24 / 3 = 8
Plot x=0, y= 1.5, and x=10, y=8 (two points)
draw a line.

2.2 X = y + 1
for convenience, interchange the left and right side
Y + 1 = 2.2 X

Now, subtract 1 fro each side to get y = 2.2 x - 1

Same as above, first set x=0, in this case y= -1

Now set x=10, so y = 22 - 1 or y = 21
The second point is x=10, y=21
Draw a line between the points

Last

2x - y = 5
2x = 5 + y
swtch sides
5 + y = 2x

Now subtract 5 from both sides
y = 2x - 5

When x = 0, y = -5
When x = 10, y = 20-5 or 15

Plot the points, draw your line.
