The second one because for every x value there is one and only one y value. If you plotted the points and graphed it, you would know it is not a function if it doesn't pass the vertical line test. Notice the same x values show up repeatedly in the other ordered pairs with different y values. Only one y value for every x value

Answer:
y = 90°
Step-by-step explanation:
The left side base angle of the triangle and the angle of 110° form a straight angle and are supplementary, thus
base angle = 180° - 110° = 70°
The right base angle is also 70° , thus the triangle is isosceles
The line segment from the vertex is a perpendicular bisector, hence
y = 90°
