Question

(7) find value of 'K'
if line 4X+ky-7=0 has slop 3​

Answer 1

Answer:

Given that 4X+ky-7=0and slope is 3 . dy/dx=3

Step-by-step explanation:

4X+ky-7=0

differentiate with respect to x

4 dx/dx+ k dy/dx -d7/dx=0 { dx/dx=1 , d7/dx=0}

4+kdy/dx=0

k dy/dx= -4

k 3= -4 {dy/dx=3}

k= -4/3 ans
