What is the slope of the line that passes thought the points (-7,-7)and(-7,1) write your answer in simplest form.
Alexxandr [17]

Answer:

The slope is undefined

Step-by-step explanation:

Find slope by using the slope formula, m=\frac{y2-y1}{x2-x1}

Use the given points and insert the x's and y's to solve for slope

(-7, -7) (-7, 1)

m=\frac{y2-y1}{x2-x1}

m=\frac{1-(-7)}{-7-(-7)}

m= \frac{8}{0}

m = undefined

The slope for the given point is undefined because it is impossible to divide a number by 0

Brainliest to the first correct answer!
Goryan [66]

Answer:

D.

Step-by-step explanation:

You know that 0.25 went to 2.00. That means that it's a 1.75 jump. In order to jump the other two prices up and keep the ratio the same, you must also jump them 1.75.

0.05 + 1.75 = 1.80

0.10 + 1.75 = 1.85

To double check the ration we can look back on the original. 0.05 to 0.10 is a scale of 0.05. 0.10 to 0.25 is a scale of 0.15

Then we look at our new one. 1.80 to 1.85 is a scale of 0.05. 1.85 to 2.00 is a scale of 0.15.

The ratios stayed the same, so this is the correct answer.

I hope this helped :)
