Which of the following best defines the x-intercept and the y-intercept of a line?

You are asked to graph the equation 2x - y = 4 using intercepts. Which set of points should you plot and then connect to produce the correct line?

A student graphs the line represented by x + 3y = 9 by plotting the intercepts (9,0) and (0,3). They also plot a third point, (1,2), to check accuracy. Are these three points collinear?

A small bakery’s profit, P (in dollars), based on x cupcakes sold is modeled by the linear equation P = -2x + 120. Using intercepts, determine how many cupcakes must be sold for the profit to be zero.

Which of the following procedures correctly produces the equation of a line given intercepts (a, 0) and (0, b) where a and b are nonzero?
