To determine which points belong to the graph of the function \(y = 4x - 9\), we can substitute the x-values from each point into the equation and see if the corresponding y-value matches. 1. \(A(2, -1.5)\): - Substitute \(x = 2\) into the equation: \(y = 4(2) - 9 = 8 - 9 = -1\) - \(y\) doesn't match \(-1.5\), so \(A\) does not belong. 2. \(B(3, 3)\): - Substitute \(x = 3\) into the equation: \(y = 4(3) - 9 = 12 - 9 = 3\) - \(y\) matches \(3\), so \(B\) does belong. 3. \(C(4, 7)\): - Substitute \(x = 4\) into the equation: \(y = 4(4) - 9 = 16 - 9 = 7\) - \(y\) matches \(7\), so \(C\) does belong. 4. \(D(-1, -15)\): - Substitute \(x = -1\) into the equation: \(y = 4(-1) - 9 = -4 - 9 = -13\) - \(y\) doesn't match \(-15\), so \(D\) does not belong. So the points \(B(3, 3)\) and \(C(4, 7)\) belong to the graph of the function.
