What is the slope of a line that passes through the points (9,-6) and (-8,7)?
lianna [129]
<h2>Answer:    slope = - ¹³/₁₇  </h2>

Step-by-step explanation:    

       The question gives us two points, (9,-6) and (-8,7), from which we can find the slope and later the equation of the line.

<u>Finding the Slope  </u>

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)    

                                         =  (7 - (- 6)) ÷ (-8 - 9)  

                                         =   - ¹³/₁₇  

<em><u>Checking my answer:</u></em>

Finding the Equation

<em>We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:</em>

<em>                                  ⇒  </em><em>y - (-6) =  - ¹³/₁₇ (x - 9)</em>

<em>                                          </em>

       

<em>To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.</em>

Kryger [21]
The answer is 26 because if you round 12.5 it would be 13 and of you would round 1.75 it would be 2. After you do this you would multiply the 2 numbers and get 26 which is your answer.

In what ways can horizontal, vertical, and oblique asymptotes be identified?
antiseptic1488 [7]
A horizontal asymptote y = a is a horizontal line which a curve approaches as x approaches positive or negative infinity. If the limit of a curve as x approaches either positive or negative infinity is a, then y=a is a horizontal asymptote.

A vertical asymptote x = b is a vertical line that a curve approaches but never crosses. The value b is not in the domain of the curve. More precisely if the limit of a curve as x approaches b is either positive or negative infinity then x=b is a vertical asymptote.

An oblique asymptote is a diagonal line (a line whose slope is either positive or negative) that a curve approaches. For a rational function R(x) = P(x) / Q (x) an oblique asymptote y = my + b is obtained by dividing P(x) by Q (x). Doing so will yield a quotient and remainder. If we set the quotient equal to y that gives the equation of the oblique asymptote.
