What are the slope and y-intercept of the graph of g?

• A

• B

• C

• D

A linear function is represented on the coordinate grid. The ​y-intercept of the graph of this function is ​b =​ (a)   and the ​slope of the graph of this function is m =​​ (b)  

Answer explanation

[RC2] 8.4(C)

Remember to look at where the line crosses the Y-AXIS to determine the y-intercept.

Slope on a graph is

m = rise/run

Notice the line goes DOWNHILL - so slope will be negative.
