Re: please solve!!

Hi runlemmingsrun1,

Here, one point and the slope are given.

So, we have to use the slope-point formula.

That is, (y - y1) = m (x - x1)

Given that, (x1,y1) = (5,4) and the slope m = 2.

           y - 4 = 2 (x - 5)

           y - 4 = 2x - 10

           y - 2x = -10 +4

           y - 2x = -6

           y - 2x +6 = 0

This is our required answer.
