Find the slope of the line that passes through the following points. Write "undefined" if the slope is undefined.
Katyanochek1 [597]

The slope of the line that passes through the following points is undefined

<em><u>Solution:</u></em>

Given that, We have to find the slope of line passing through two points

Given points are (-1, 5) and (-1, 6)

<em><u>The slope of line is given by formula:</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

From given,

(x_1, y_1) = (-1, 5)\\\\(x_2, y_2) = (-1, 6)

<em><u>Substituting the values we get,</u></em>

m = \frac{6-5}{-1-(-1)}\\\\m = \frac{1}{-1+1}\\\\m = \frac{1}{0}

Thus the slope is undefined

One number is 3 less than 5 times another number. The sum of the numbers is 27. What are the two numbers? Enter your answers in
kaheart [24]

x ,y are the numbers

x = 5y-3

x+y = 27

substitute first equation into the second

(5y-3) +y =27

combine like terms

6y-3=27

add 3 to each side

6y=30

divide by 6

y=5

x = 5y-3

x=5*5-3

x=22

the two numbers are 22 and 5
