Question

John and Bob are house painters. The graph here shows how many rooms each can paint during the same length of time. How much faster can John paint?

Answer 1

Take a pic of the graph so we know what the data shows!!

Answer 2

Answer:

John paints 3 times as fast as Bob

Step-by-step explanation:

There are two ways to determine this. You can take the value for John and divide it by the value for Bob at any point on the graph. It’s much easier to just take the value for John when Bob has painted 1 room. John has painted 3 rooms, so John paints three times as fast as Bob. This is a graph of the equation y = 3x. The ratio of y to x at any point on this graph is known as the slope of the graph and is equal to k.
