Which of the following has the least steep graph?
aleksklad [387]
Answer is D. y = 1/2x + 3
Explanation
you are looking for “least steep” on the graph, so you are looking for the least amount of slope. Slope is the number next to x in the slope intercept y=mx+b.
1/2 on a graph would be 1 up and 2 to the right
The other three options would be 1 up 1 over, 2 up 1 over, 3 up 1 over, all having a steeper slope.
