What is the change in y- values for every two units of x-values?
schepotkina [342]

Answer:

The graph of y\:=\:\frac{1}{2}x  is also attached below, which indicates that there is a change of only one unit on the y-axis for every two units of x-values.

Step-by-step explanation:

When there is a change in x values, it is basically a horizontal change. horizontal change between two values is also called the run.

And the vertically change between two values is also called the rise.

The slope is basically the ratio of the vertical (rise) and horizontal (run) changes between two points on a line.

For example, consider the equation

y\:=\:\frac{1}{2}x

\mathrm{Slope\:of\:}\frac{1}{2}x:\quad m=\frac{1}{2}

Here fore every two units of x-values, one units are moved on the y-axis.

In other words, there is a change of only one unit on the y-axis for every two units of x-values.

The graph of y\:=\:\frac{1}{2}x  is also attached below which is showing this.

Mary spent half of her allowance going to the movies. She washed the family car and earned seven dollars. What is her weekly all
Nata [24]

Answer:If Mary spent half of her allowance the equation will begin with 1/2x or 0.5x where x is her allowance and 0.5 is half of her allowance spent. Mary also earned 7 dollars by washing the car so this will be added to her allowance spent.

The problem says that after Mary has spent half of her allowance at the movies she was left with 18 dollars so that means that the equation must be equal to 18.

The equation you want to set up is

0.5x+7=18

Where, 18-7=11

0.5x=11

11/.5 = x

x = $22

Thus, Mary has a weekly allowance of 22 dollars.
