Hi!
The answer is B. Linear function.
A linear function is when the change in <em>y </em>and <em>x</em><em> </em>is constant. For example, let's make some <em>x</em> and <em>y</em> values.
x 1, 2, 3, 4, 5
y 2, 4, 6, 8, 10
When <em>x</em> increases by 1, <em>y</em> increases by 2. The change in <em>x</em> and <em>y </em>is constant, therefore, that is a linear function.
x 6, 9, 13, 26
y 3, 5, 10, 11
There is no pattern in those numbers, therefore this is not a linear function.
Hope this helps! :)

Answer:
C. 
Step-by-step explanation:
Let x represent number of miles.
We have been given that a taxi cab charges $1.50 for the flat fee and $0.50 for each mile.
The cost of riding x miles would be
and the total cost of riding x miles would be
.
Since Sharon has only $25 to spend on the taxi ride, so the cost of riding x miles on taxi must be less than or equal to 25.
We can represent this information in an inequality as:

Therefore, option C is the correct choice.

Answer:
M(3, 2) and N(3, 1)
Step-by-step explanation:
A rectangle was rotated 270° about the origin.
Since it doesn't mention which direction, we will review both clockwise and anti-clockwise rotation.
See attached where top rectangle represents the pre-image before anti-clockwise and bottom one - before clockwise rotation.
<u>Now let's check the points given:</u>
K(–3, –1)
M(–3, 2)
M(3, 2)
N(–3, 1)
N(3, 1)
So based on correct points of pre-image we can state it was rotation anti-clockwise
