Use an equation to find the value of k so that the line that passes through the given slope (1,3) , (5,k) m=2

scoray [572]

Answer:

The value of k with given points and slop = 11

Step-by-step explanation:

Given that a line passes through two points having slop (m) = 2

co ordinates of points are (1 , 3) and (5 , k)

Now slop of line can be written as,

Slop = $\frac{(y2 - y1)}{(x2 - x1)}$

Or, m = $\frac{(y2 - y1)}{(x2 - x1)}$

2 = $\frac{(k - 3)}{(5 - 1)}$

Or, 2 = $\frac{(k - 3)}{(4)}$

So , k - 3 = 8

∴ K = 8+3 = 11

Hence the value of k with given points and slop = 11 Answer
