Answer:
undefined
Step-by-step explanation:
The slope formula tells you the slope is ...
m = (y2 -y1)/(x2 -x1)
Fill in the point coordinates, we find the slope to be ...
m = (6 -9)/(-5 -(-5)) = -3/0
This slope is undefined.
___
It means the line is a vertical line. The constant must match the x-coordinates of the points:
x = -5 . . . . the line through the given points
Answer:
they should buy 10 boxes
Step-by-step explanation:
300/30 = 10
Answer:
The vertical line test is a way for you to see if a graph represents a function. It allows you to identify if any x values have more than one y value.
A graph would be a function if every input (x) has exactly one output (y). A graph would not be a function if an input (x) has more than one output (y).
Step-by-step explanation:
In a function, every input within the domain of the function must have exactly one output. If the graph has an input that has more than one output, then it is not a function. The vertical line test is what allows you to see if a graph is a function or not.
Ok, let's find how much does 1 yard of ribbon cost. Let's divide!

Each yard costs $1.50, so let's multiply that by 10

Marci will pay $15 for 10 yards of the ribbon.
