Question

Question: Complete the point-slope equation of the line through (1,3)and (5,1). Use exact numbers. Equation: y-3=(Answer ?)

Answer 1

y - 3 = -1/2(x - 1)

Explanation:

Hey there!

Well point slope form is,

`y - y_(1) = m(x - x_(1))`

We can use the point (1,3)

y - 3 = m(x - 1)

Now we need to find slope with the following formula,

`(y^2-y^1)/(x^2-x^1)`, we’ll use the points (1,3) and (5,1).

`(1-3)/(5-1)`

-2/4

Slope or m = -1/2

y - 3 = -1/2(x - 1)

Hope this helps :)
