#11
The steepest slope would be m=5
This is the same as 5/1 so you are going UP 5 units for every one unit movement right.
#12
y=mx+b
The b is where it crosses the y axis. This is -2.
The slope is negative because it FALLS from left to right.
Rise/run is 2/7 so slope is -2/7
y = -2/7x -2

Does this graph show a function explain how you know
Semenov [28]

The correct option is Option D: Yes, the graph passes the vertical line test.

The function is a relationship between two distinct sets X and set Y which can be many-one or one-one. here set X is called the domain and set Y is called the codomain.

The vertical line test states that

If we draw a straight vertical line( which is also parallel to the y-axis) and it touches the graph at only one point at all locations, then that relation is said to be a function and this relation will be also one-one.

So here in this function shown in the graph.

If we draw a vertical line parallel to the y-axis in this at any location then it crosses the graph only once. So, it passes vertical line test. And this graph is a function. Therefore option D is correct.

Anit [1.1K]
Let 0.25x is the price increase. Therefore, the number of attendees will be 350-10x and the revenue R=(350-10x)*(5+0.25x)=1750+37.5x-2.5x^2. This parabola has maximum at x=10, meaning the price=7.5
