find slope of the line giving brianly make sure to explain

Answer: D 6
Step-by-step explanation:
To find the slop you do rise/run. You find where a point is exactly on a line and find the rise and the run difference. In this question the two easiest points to figure out is (0,-3) and (1,3). The rise (or the difference in y) is 6 and the run (or difference in x ) is 1. 6/1=6.
