Question

The slope of the the line joining the points(2,k-3) and (4,-7) is 3 .the value of k will be ???? Please answer right

Answer 1

hope it helps best of lick for icse...iam too a icse student



y2 - y1 / x2 - x1

-7-(k-3)/4-2

-7-k+3/2

-k-4/2

as we know slope=3
so,
3=-k-4/2

6=-k-4
-k=10

k=-10

Answer 2

3 =-7-(k-3)/4-2

3=7-k+3/2

6=10-k
