What is the slope of this line?
Brums [2.3K]

Answer:

slope=\frac{1}{4}

Step-by-step explanation:

The slope of a line can be seen as:

\frac{rise}{run}

Rise over run is the change in the y values over the change in x values. For example, in this graph, you would start on one of the points given. From there, you would move up first. After moving up a certain number of spaces, you would move to the side until you reach the other point.

In the graph, you would move up until you are in line with one of the other points. Starting at (-4,5), move up one space, then to the left 4 spaces to reach the point (0,6). Using the spaces moved in the rise over run:

\frac{1}{4} =\frac{rise}{run}=slope

Therefore, the slope is \frac{1}{4}.

This is true for any two points on the line.

:Done

*When you move up, the number will be positive (\frac{+y}{x} ). If you move down, the number will be negative (\frac{-y}{x} ). If you move left, the number will be positive (\frac{y}{+x}). If you move right, the number will be negative (\frac{y}{-x} ). Keep this in mind. It is very important.

**Always <em>move along the y-axis first</em>, then move along the x-axis. If you do it the other way, the slope will be wrong.

Y=x^2 is y a function of x​
Digiron [165]
Yes y=x^2 is a function because Using the definition of a function, y=x^2 is a function because for every x-value in your domain, you will only get 1 unique y-value. A quick check you can do is to use the vertical line test

The jewelry center bought a pair of earrings for $250. They are going to mark the price of the earrings up 32.5%. How much will
ELEN [110]

Answer:

$331.25

Step-by-step explanation:

Given:

The jewelry center bought a pair of earrings for $250

They are going to mark the price of the earrings up 32.5%

Question asked:

How much will they sell the earrings for ?

Solution:

Cost price of a pair of earrings =  $250

Mark up value = 32.5% of $250

                        = \frac{32.5}{100}  \times 250\\\frac{8125}{100} = 81.25

Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.

Selling price = cost price + mark up value

                     = 250 + 81.25

                     = $331.25

Thus, they sell the earrings for  $331.25
