Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
John gets a new job and receives a $800 signing bonus. After that, he makes $400 a day. [x = the number of days y = total earnings]
y = 400x + 800
[John earns $400 per day(x) plus a signing bonus(initial payment before working) of $800 = total amount of money he earns]
The slope is 400 or [tex]\frac{400}{1}[/tex]
The y-intercept is 800
