Simple...

y=x^{2} -9

y= x^{2} -9

It's quite easy to see x^{2} = x^{2}

Thus, any value of x makes the equation true.

Thus, your answer.

Carla bought a piece of ribbon that measured 1 meter in length. She used 1/4 of the ribbon on a gift box. She used 1/8 of the ri
lord [1]

1/4 is equal to 2/8.

2/8+1/8=3/8

Carla used 3/8 of the ribbon in all. So, 5/8 of the ribbon is left.

I hope this helps :)

Find the slope of the line passing through the points (7, 8) and (-7, 1). Show your work.
anygoal [31]

Answer:

The slope is \frac{1}{2}

Step-by-step explanation:

∵ The rule of the slope passing through 2 points is:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

∵ The points are (7 , 8) and (-7 , 1)

∴ m = \frac{1-8}{-7-7}=\frac{-7}{-14}=\frac{1}{2}

Line m includes the points (-3, 3) and (-4,-6). Line n has the same slope as line m and
Sveta_85 [38]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

The slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

We have that the line m passes through the following points:

(x_ {1}, y_ {1}): (-3,3)\\(x_ {2}, y_ {2}): (-4, -6)

So, the slope of the line m is:

m = \frac {-6-3} {- 4 - (- 3)} = \frac {-9} {- 4 + 3} = \frac {-9} {- 1} = 9

Line n has the same slope so the equation is of the form:

y = 9x + b

We have as data that the y-intercept is -\frac{2} {3}. Thus, we have that the equation of line n is:

y = 9x- \frac {2} {3}

ANswer:

y = 9x-\frac {2} {3}
