Drag each system of equations to the correct location on the graph. Match each system of equations to its point of intersection.

y = 2x + 1 y = x + 3

y = x + 3 y = -3x - 2

y = -x - 7 y=-x - 7

y = x + 3 y = 2x + 1

y =2x + 1

y =-3x - 2

These tables represent a quadratic function with a vertex at (0, -1). what is the average rate of change for the interval from x = 9 to x = 10?

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

Which statements describe the solutions to the inequality x< -20 check all that apply. there are infinite solutions. each solution is negative. each solution is positive. the solutions are both positive and negative. the solutions contain only integer values. the solutions contain rational number values.
