Why won’t anyone answer my questions argh! how do you draw starlight line graphs
Oduvanchick [21]
The table tells us that the x coordinate. It also tells us that y is always x + 1.

For #1 you plot the coordinate (0, 1).
0 (the x coordinate) is given to us already.
1 (the y coordinate) is needed to be found by the equation.
You would then need to fill in the equation given with the x coorident. 
y = 0 + 1 
Then, solve for y.
0 + 1 = 1
The y coordinate is 1
Go to the horizontal line (x) and find 0.
Then go to the veridical line (y) and find 1.
Then match up the the x and y to plot the coordinate.

You would continue with this equation with the rest of the xs. 

This is a hard concept to explain in just words, so feel free to comment with any more questions. :D
