Answer:
<u>Find the slope:</u>
<u>Use point-slope form and one of the points:</u>
- y - y₁ = m(x - x₁)

Answer:
A
Step-by-step explanation:
Lets first solve the relation for "y". Shown below:

This is clearly an equation of a line in the form 
It will be a negatively sloped line, when graphed.
We can use vertical line test to determine function or relation. If a vertical line passes through only 1 point in the graph, we say that it is a function.
Think of a negatively sloped line. No matter where you draw a vertical line, it will only cut the line at 1 point.
So, this is definitely an equation of a function
Correct answer is A
Answer:
17
Step-by-step explanation:
6ft and 2 in === 74 in
4ft and 9 in === 57 in
