What is the solution to the following system of equations?

4x + 2y = 6
x − y = 3

A). (2, 1)
B). (−2, −1)
C). (2, 4)
D). (2, −1)

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

Can someone me with the property questions for 12 13 and 14 plz
