Answer:

y = - 1/4 x

Step-by-step explanation:

Look for the slope of this graph.

Take for an example of a point. Let's take (-4,1) and (0,0)

Now let's see how many downs and rights needed to go from (-4,1) to the origin (0,0).

As you can see, it goes 1 down and 4 rights.

So now you know the slope of the line which mean you can choose one of the choices now.

1 down, means negative one (-1), will be a numerator of the slope fraction and 4 right, meaning positive four (4), will be a denominator of the slope fraction.

<em>Note: This method is only available when you see two easy points to determine. In most cases you have to do the math using the slope formula.</em>

A movie theater charges $5 per ticket and averages 300 customers each night. If prices are raised to $7 per ticket, the theater

Shtirlitz [24]

Attendance with the higher ticket price is ...

... $1750/$7 = 250

So the percentage change in attendance is ...

... change = (new - original)/original × 100%

... = (250 -300)/300 × 100% = -1/6×100% ≈ -17%

Which expression is the same as 10÷4?

prisoha [69]

10/4 is not the simplified version that it can be. So 5/2 would be the same expression.

Which equation represents a linear function?

Mila [183]

The equation y - 2 = -5(x - 2) represents a linear function ⇒ 1st answer

Step-by-step explanation:

A linear function is any function that graphs to a straight line

(not a vertical line)

The forms of the linear equation are

y = m x + b, where m is the slope of the line which represents the function and b is the y-intercept ⇒ slope-intercept form
$y-y_{1}=m(x-x_{1})$ , where m is the slope and $(x_{1},y_{1})$ is a point lies on the line which represent the function ⇒ slope-point form
Ax + By = C, where A, B, and C are constant ⇒ standard form

Linear function means the greatest power x and y in the equation of the function is 1

∵ The equation is y - 2 = -5(x - 2)

∵ The greatest power of x and y is 1

∵ The equation is in the form of $y-y_{1}=m(x-x_{1})$ , where

m = -5 and the coordinates of the point are (2 , 2)

∴ The equation represents a linear function

The equation y - 2 = -5(x - 2) represents a linear function
