How can you use the point-slope form of a line when only given two points?

Mathematics

Answer:

See below

Step-by-step explanation:

<u>Point -slope form is:</u>

  • y - y1 = m(x - x1)

By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.

<u>How to find the slope?</u>

Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2

<u>Use the formula:</u>

  • m = (y2-y1)/(x2-x1)

<u>Example:</u>

  • m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
  • y - 2 = -5(x - 9)

If 2(x - 5) + 3(x - 5) = 10, what is the value of x - 5?
sleet_krkn [62]

Answer:

x + 5 divided by x - 5 = 10

Then we can solve it as

x + 5 = 10 ( x - 5 )

x + 5 = 10x - 50

Collecting the variables to one side & numericals to other side then the equation becomes

10x - x = 5 + 50

or 9x = 55

Therefore x = 55/9

If this is not what you wrote then please check Mr. Thornton’s reply.
