Explanation:
For now ignore the inequalities, you can replace them by =
So,
You have y=1 first right?
This one is pretty simple it's where y is 1. x can change but y needs to stay 1. Find 1 on the line y and draw your line there. (orange line)
Next, y = 2x+2
You can do a littleeee table to find the coordinates of this line.
You give x any random value and replace it in the equation y and get y.

For example here, we used 0 and 2 as x.
Y = 0(2)+2 = 0+2 = 2
Y = 2(1)+2 = 2+2 = 4
So we got two coordinates. (0,2) and (1,4)
Plot your points, and then use your ruler to draw the line.
(red line)
Next, x+y=3
This one you have to go to the x and y axis both and take 3 as your points and draw your line. (you go the the x axis and take 3 there, go to the y axis and take 3 there too)
(blue line)
Now, the inequalities. If you have > then it means the line is broken
If there is a line below the > (>=) then it's a solid line. I hope you understand why I broke the red and yellow lines now. But you can ignore this if it confuses you.
Just know if you have a:
• Horizontal or diagonal line, > is for above the line and < is for below the line
• Vertical, > is for right, < is for left.
It indicates the direction where the area should be
That's how you find R
