Which graph could Catherine use to solve the equation 4x=30

Question

?

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.

A graph of 2 lines. One is a vertical line at x = 30. The other is a line that slopes up from left to right. It goes through the points (0, 0) and (20, 20). This line intersects the vertical line at (30, 30).

Answer 1

The appropriate graph that Catherine could use to solve the equation 4x = 30 would be the graph with two lines. One line is a horizontal line at y = 30, and the other line slopes up from left to right and goes through the points (0, 0) and (2, 20). This line intersects the horizontal line at (3, 30).
