Your y is always the dependent variable, or the value that changes when another value changes
So which one depends on the other, between the 'money for school charity' and 'number of lawns mowed'? the money for charity depends on how lawns are mowed, so this is y
Now we have y, and we already know it depends on the number of loans mowed, so number of lawns mowed is x
So an equation in the form [tex]y=mx+b[/tex] is a slope-intercept form where m is the slope and b is just a constant number, in this case b is 0.
so we have [tex]y=mx[/tex]
Now the slope m is interesting because it is the "amount of change"
Let's ask ourselves, when Donny mows one lawn he gets, 9.75 dollars, and when he mows 2 lawns he gets 19.5 dollars
The amount change here is 9.75, so that's our slope m is 9.75
