Which of the following best defines the x-intercept and the y-intercept of a line?
Determine the intercepts of the line given by y=34x−6y=\(\frac\)34x-6, and state the ordered pairs.
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?
A student finds intercepts of 2x - y = 4 as (2,0) and (0,-4). They pick an arbitrary third point by setting x = 4 and computing y to be 8, then plot (4,8). Is the student's third point correct?
