Equation from a Graph - Kelly Andrews Denney | Library

This practice will focus on finding the equation from a graph. For a general explanation of how to do that, watch the following video.
To see four examples of finding the equation from a graph, watch the video below.

1

What is the y-intercept of the graph below? (this would often be a coordinate, but just think about what you would substitute for "b" in y=mx+b)

1

What is the slope of the graph below? (what would you substitute for "m" in y=mx+b)
