SLO Review #1

Is this function linear or nonlinear?

• Linear
• Nonlinear

Is the graph pictured a linear or nonlinear function?

• Linear
• Nonlinear

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Is this table a function and how can you tell?

• Yes its a function because there are not variables for missing numbers
• No it's not a function because the y value 4 repeated
• No it isn't a function because the x value 2 is repeated
• No it's not a function because the x value 5 has y values of  10 & 12

• Function
• Not a Function

Is the function represented by the table linear or nonlinear?

• Linear

• Nonlinear

How is the distance formula correctly written:

• $d\ =\ \sqrt{\left(y_{1\ }-\ y_2\right)^2\ -\left(x_{2\ }-\ x_1\right)^2}\$

• $d\ =\ \sqrt{\left(x_{2\ }-\ x_1\right)^2\ +\ \left(y_{2_{\ }}-\ y_1\ \right)2}$

• $d\ =\ \sqrt{\left(y_{1\ }-\ y\ _2\right)^2\ +\ \left(x_{2\ }-\ x_1\right)}^2$

• d = $\sqrt{\left(x\right)^2-\ \left(y\right)^2}$

Find the distance between (-5, -8) and (-1, -16).

• 8.9
• 9.8
• 10.3
• 11

Find the distance between (3, 24) and (7, 56).

• 32.1
• 32.2
• 32.3
• 32.4

Using the Slope Formula

 $\frac{y_2-y_1}{x_2-x_1}\ \ \ \left(x_1,\ y_1\right)\left(x_2,\ y_2\right)$  
Find the slope of the line that passes through these two points:
 $\left(-2,\ -2\right)\left(1,\ 2\right)$  

•  $\frac{5}{3}$  

•  $1$  

•  $\frac{4}{3}$  

•  $\frac{3}{4}$
