The table shows the grade, g, on a test when the number of problems, n, are correct. Write an equation to model the situation. n 10 18 21 g 40 72 84(1 point) Responses n = 4g n = 4g g = 4n g = 4n g = n + 30 g = n + 30 n = g - 30

Answer 1

The correct equation to model the situation is g = 4n.

Answer 2

The equation y=6x+6 describes the relationship between quantities x and y. Are the quantities in a proportional relationship?(1 point) Responses Yes, because the graph of the equation is a straight line. Yes, because the graph of the equation is a straight line. Yes, because the graph of the equation passes through the origin. Yes, because the graph of the equation passes through the origin. No, because the graph of the equation is not a straight line. No, because the graph of the equation is not a straight line. No, because the graph of the equation does not pass through the origin.

Answer 3

No, because the graph of the equation is not a straight line.

Answer 4
