Answer:
Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

Answer:
y = -8x
Step-by-step explanation:
First let's look at what slope-intercept form is.
y = mx + b
m is the slope, which in this case is -8.
b is the y-intercept, which we will find later.
Now that we have identified the parts of the equation, let's plug in what we know. Use the point given for your x and y values.
y = mx + b
16 = -8(-2) + b
Let's simplify this to find b.
[multiply] 16 = 16 + b
[subtract 16] 0 = b
We now have our b-value, which is also our y-intercept. Plug in this value into the standard slope-intercept equation.
y = -8x
This is your equation.
Check this by plugging in the point again.
16 = -8(-2)
[multiply] 16 = 16
This expression is true; therefore, your answer is correct.
Hope this helps!
Answer:
Liz's annual pension is $1470
Step-by-step explanation:
Salaries for the last four years are $66,000; $66,000; $73,000; and $75,000
Finding the average salary in the four years will be;
Sum $66,000 + $66,000 + $73,000 + $75,000 =$280,000
Number of years =4
Average= $70,000
Applying 2.1 % pension
$70,000 * 2.1/100 =$1470 annual pension
