Question

Jeremy has a weekend job as a soccer referee. One weekend, he earns $140 by working 4 games. Another weekend, he earns $210 by working 6 games. If Jeremy graphed an equation that would represent his total earnings based on the number of games worked, what would be the slope of the graph?

Answer 1

Jeremy's weekend work would follow the equation of the standard line. The equation of the standard line is y=mx+b. b= 0, The slope of the line is equal to m, where m according to the given problem is equal to 35. Every hour of Jeremy weekend would pay $35. 
Jeremy's equation
y= 35x
m=35
