Answer 2

Checking Points on the Graph of y=1.5x+1

To determine if the points A(-2,-2), B(-1,-1), C(1,2), and D(2,4) belong to the graph of the function y=1.5x+1, we can substitute the x-coordinates of the points into the function and check if the resulting y-coordinates match the given points.

- For point A(-2,-2): - Substituting x=-2 into the function y=1.5x+1 gives: - y = 1.5*(-2) + 1 - y = -3 + 1 - y = -2 - The resulting y-coordinate matches the given y-coordinate of point A(-2,-2).

- For point B(-1,-1): - Substituting x=-1 into the function y=1.5x+1 gives: - y = 1.5*(-1) + 1 - y = -1.5 + 1 - y = -0.5 - The resulting y-coordinate does not match the given y-coordinate of point B(-1,-1).

- For point C(1,2): - Substituting x=1 into the function y=1.5x+1 gives: - y = 1.5*1 + 1 - y = 1.5 + 1 - y = 2.5 - The resulting y-coordinate does not match the given y-coordinate of point C(1,2).

- For point D(2,4): - Substituting x=2 into the function y=1.5x+1 gives: - y = 1.5*2 + 1 - y = 3 + 1 - y = 4 - The resulting y-coordinate matches the given y-coordinate of point D(2,4).

Conclusion: - Points A(-2,-2) and D(2,4) belong to the graph of the function y=1.5x+1, while points B(-1,-1) and C(1,2) do not belong to the graph.

Summary:

Based on the calculations, points A(-2,-2) and D(2,4) belong to the graph of the function y=1.5x+1, while points B(-1,-1) and C(1,2) do not belong to the graph.
