The linear equation y = 400 + 50x represents the total cost, y, per hour, x, for a lawyer at a law firm. The lawyer charges a flat retainer fee and then charges per hour of work done.

Groups:

(a) True

,

(b) False

• The slope represents the cost of work per hour

• The y-intercept is 50

• The y-intecept represents the flat retainer fee

• The slope of the line is 400
