Using the slope formula, find the slope of the line through the points (0,0) and (4,8) . Use pencil and paper. Explain how you can use mental math to find the slope of the line
Look below! I hope this helps, and mark as brainliest please!
Step-by-step explanation:
The formula for slope is (y2-y1) divided by (x2-x1). So in this case, we have (8-0) divided by (4-0) so we get 8 over 4 and that is 2. So the slope is 2.
