Question5. Which are examples of LINEAR functions? Circle all that apply. x+2y=6x+2 y=6 y=3y=3 x2+y2=4x^{2}+y^{2}=4 y=x2y=x-2 y=12x3y=\frac{1}{2} x^{3} y=12xy=\frac{1}{2} x y=xy=\sqrt{x} \begin{tabular}{|l|l|} \hlineXX & YY \\ \hline 0 & 0 \\ \hline 1 & 1 \\ \hline 2 & 4 \\ \hline 3 & 9 \\ \hline \end{tabular} \begin{tabular}{|c|c|c|c|c|c|} \hlinexx & -2 & -1 & 0 & 1 & 2 \\ \hlineyy & -3 & -1 & 1 & 3 & 5 \\ \hline \end{tabular}

6. Which graph best represents the equation 4x+6y=124 x+6 y=12 ? Don A. c. B.
7. A hot air balloon is at an altitude of 400 feet. It begins to descend at a rate of 100 feet per minute. Graph this scenario below.  Identify: 80x+4\text { Identify: } 80 x+4

Slope: \qquad Y-intercept: \qquad 400.

Studdy Solution
The linear functions from the list are: - x+2y=6x + 2y = 6 - y=3y = 3 - y=x2y = x - 2 - y=12xy = \frac{1}{2}x
The second table represents a linear function.
A linear graph looks like a straight line.
