What point would be included on the additive graph y=x+8?

Plot it on a graph ! The y intercept is 8, so start there. The slope is 1/1, and it is positive.

So, these means we need to rise (1) and then run (1). Rise up by one point, and then run to the left by one point. Continue the process, and bam! You got yourself a line.

Hmmm i had this before , give me a sec

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
