Ms. Magier tried to graph the linear equation
y=1/4x+3.
What mistake did she make?
Slope of the graph is 4/1 instead of 1/4 - Ms. Magier switched rise and run.

The equation for the line of best fit that represents the relationship between hours spent playing video games (g) and hours spent doing homework (h) in one week is:
g=-1.5h+23
What does the slope represent in context of the situation?
For each additional hour spent doing homework, time spent playing video games decreases by 1.5 hours.
