Question

Andy found three ordered pairs - (0, 250), (5, 575), and (10, 900) - for the equation, y = 65x + 250. When he graphs these, what is the minimum range for the y-axis?

65 to 250

0 to 10

0 to 250

0 to 900

Answer 1

Well, we know that since y=65x+250, there are no negative signs, and we also know that when the function is at x=0, the y value is 250.
He has to go 0 to 900 to include all the points because if he didn't, and only went from 0 to 250, he wouldn't be able to plot the points (5,575) or (10,900)
so he has to go 0 to 900.
do you understand?
