Question 107490
Your equation is already in the slope-intercept form,


{{{y=mx+b}}}


where m is the slope and b is the y-intercept.


In the case of


{{{y=1.25x}}}


the value of the intercept is 0.


The slope in this case is just the coefficient on the x term, or 1.25.  That means that Mohammad makes $1.25 for every tire he makes, and, since the slope is positive, the more work he does, the more money he makes.


The intercept in this case is zero, so any time Mohammad takes a vacation day and doesn't make any tires at all, his pay for that day is also zero.
