Which graph could Catherine use to solve the equation 4x=30
?
CLEAR CHECK
A graph of a straight line and a curve. There is a horizontal line at y = 30. The curve approaches 0 as x heads to negative infinity. The curve goes through the points (0, 4) and (2, 16). It intersects the line at about x = 2.5
A graph of 2 lines. One is a horizontal line at y = 30. The other is a line that slopes up from left to right. It goes through the points (0, 0) and (2, 20). This line intersects the horizontal line at (3, 30).
A graph of a straight line and a curve. There is a vertical line at x = 30. The curve approaches 0 as x heads to negative infinity. The curve goes through points near (0, 4) and (2.5, 50). The curve does not intersect the line.
