kayla, a photographer, can produce prints of her photos at a cost of $4 per print, with a setup cost of $45 per run. she sells the prints for $10 each. write an equation for the total cost. let c represent the total cost and x represent the number of photos produced. graph the equation by hand. use the graph to determine the cost of producing 7 prints.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
