Classify the relations according to whether or not they are functions. x = -3 y = 10 3x + 2x = 3 Graph shows a function plotted on a coordinate plane in quadrant 1. Curve begins at the origin, rises, and goes through (1, 1), (4, 2), (8, 3). Graph shows a line plotted on a coordinate plane. The line is parallel to X-axis and intersects Y-axis at 2. {(-2, 6), (-3, 7), (-4, 8), (-3, 10)}
