Find the equation of the line passing through the point (–1, –2) and perpendicular to the line y = –1∕2x + 5. Question options:
tankabanditka [31]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question

y = - 1/2x + 5

Comparing with the general equation above

Slope / m = -1/2

Since the lines are perpendicular to each other the slope of the other line is the negative inverse of the original line

That's

Slope of the perpendicular line = 2

Equation of the line using point (–1, –2) and slope 2 is

y + 2 = 2( x + 1)

y + 2 = 2x + 2

y = 2x + 2 - 2

We have the final answer as

<h3>y = 2x</h3>

Hope this helps you

If it rains, then the game will be canceled <br><br> Hypothesis:<br> Conclusion:
yarga [219]
<h3>Answers:</h3>

Hypothesis = It rains

Conclusion = The game is canceled

=====================================================

Explanation:

The general format for a conditional is "If P, then Q".

P is the hypothesis and Q is the conclusion. They are placeholders.

In this case

  • P = It rains
  • Q = The game is canceled

Some textbooks will write P \to Q to indicate "if P, then Q"
