The equation X squared plus Y squared minus 2X plus 7Y +1 equals zero can be written as which of the following equations
ad-work [718]

For this case we must write in algebraic symbology the expression described above:

We have an equation, then:

  • x squared plus y squared: x ^ 2 + y ^ 2
  • minus 2x plus 7y plus 1: -2x + 7y + 1
  • equals zero: = 0

We construct the equation:

x ^ 2 + y ^ 2-2x + 7y + 1 = 0

Find the slope of the line passing through the points (-6,5) and (6,2).​
DochEvi [55]

Answer:

If you want a fraction it would be -1/4 if you want a decimal it would be -0.25

Step-by-step explanation:

You have to take your X2- your X1 and you take your Y2- your Y1

Then you divide Y/X

So Your X2 would be 6 and X1 would be -6 and that would become a positive 12.

And your Y2 would be 2 and your Y1 would be 5 which would give you -3 when you subtract.

Then divide it 12/-3 which would give you -1/4 since you have to flip your fraction.

I hope this helps
