Question

Completet the equation of the line through(3,1) and (4,7)

Answer 1

Explanation:

GIVEN POINTS

( 3 , 1) and ( 4 , 7)

First calculating slope (m)

= (y2 - y1 )/(x2 - x1)

= ( 7 - 1) /(4 - 3)

= 6/1

= 6

Now the equation of line is given by

y - y1 = m(x - x1)

y - 1 = 6 ( x - 3)

y - 1 = 6x - 18

6x - y = - 1 + 18

6x - y = 17

6x - y - 17 = 0

Hope it will help :)
