The equation 2x+3y=39 matches the description "linear equation."
The graph consists of a curve that opens upwards and is symmetrical about the y-axis. The vertex is at the origin (0,0) and the curve passes through the points (1,5), (-1,5), and (2,14).
The table shows the values of x and y that satisfy the equation. For example, when x=0, y=2; when x=1, y=5; when x=2, y=10, etc.
