Write an equation of the line that passes through(2,7) and (0,-5)
SVETLANKA909090 [29]

Answer:

-6x + y = -5\:or\:y = 6x - 5

Step-by-step explanation:

First, find the <em>rate of </em><em>change</em><em> </em>[<em>slope</em>]:

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

\frac{-7 - 5}{-2 ± 0} = \frac{-12}{-2} = 6

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope</em><em> </em><em>Formula</em><em> </em>because you get it done much swiftly. In this case, we have a y-intercept of [0, -5], so this is a giveaway. It does not matter which ordered pair you choose:

-5 = b \\ \\ y = 6x - 5

If you want it in <em>Standard</em><em> </em><em>Form</em>:

y = 6x - 5

- 6x - 6x

_________

-6x + y = -5

_______________________________________________

7 = 6[2] + b

12

-5 = b \\ \\ y = 6x - 5

y = 6x - 5

- 6x - 6x

_________

-6x + y = -5

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

I am joyous to assist you anytime.

What are the coordinates of the point on the directed line segment from (3, -3) to
erastova [34]

Answer:

  • (5.5, 2)

Step-by-step explanation:

<u>Points given:</u>

  • (3, -3) and  (7,5)

<u>Partition ratio: </u>

  • 5 to 3

<u>Formula for the point:</u>

  • x = x1 + a/(a+b)×(x2 - x1)
  • y = y1 + a/(a +b)×(y2 - y1)

<u>So the points are:</u>

  • x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5
  • y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2
