Question

Tom and Philip were given the graph of a linear function and asked to find the slope. Tom says that the slope is 12 while Philip says that the slope is 2.

Which reason correctly justifies Tom's answer?

Answer 1

Answer

Since there is no graph or equation I can only tell you Tom and Philip need to use rise over run to find slope on a graph.

If they have points on the graph or points on a table, they can use slope formula

y2 - y1 over x2 - x1
