The lines graphed below are parallel. the slope of the red line is -. what is the slope of the green line?

Because the lines are parallel, the lines have the same slope. I can tell by the direction of the lines, that they are negative. Therefore it is either C or D. The line is 4 points up the y axis (rise) and 3 points up the x-axis (run). Using rise over run, the slope is -4/3, or C.

Use photo math it it’s so good
