Question
For each situation, determine the slope and y-intercept of the graph of the equation that
describes the situation.
John gets a new job and receives a $800 signing bonus. After that, he makes $400 a day.
The slope is
The y-intercept is

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

The y-intercept is 800
