For each table, graph and equation, select whether it is linear and whether it is a function.(6 points)
1. (y + 7) = 3 (x - 2)
2. its an graph that is shaped like an L
3.It's an +graph but the shape is an circle but is not on the line is have on the line
4. X 1,2, 3, 4, 5, 6, 7
Y 1,8,27,64,125,216,?
5. time (hours) : 3,6,9,12
temperture( degree celsius) : 5,0,-5,-10
6. 25=x2 + y2
1. Equation: Linear, Function
This equation is written in the form y = mx + b and represents a line. It is a function because for each x value, there is only one corresponding y value.
2. Graph: Not linear, Not a function
An L-shaped graph is not a linear function because it does not have a constant rate of change. Also, it is not a function because there are multiple y values for the same x value.
3. Graph: Not linear, Not a function
A circular graph is not linear because it does not represent a straight line. Also, it is not a function because there are multiple y values for the same x value.
4. Table: Not linear, Function
The y values are not increasing at a constant rate as x increases, so it is not a linear relationship. However, it is a function because each x value has a unique y value.
5. Table: Not linear, Function
The temperature is decreasing by 5 degrees Celsius for every 3 hours, so it is not a linear relationship. However, it is a function because each time value has a unique temperature value.
6. Equation: Not linear, Not a function
This equation represents a circle because it includes both x^2 and y^2 terms. It is not a linear relationship because it does not represent a straight line. Also, it is not a function because there are multiple y values for the same x value.
