Question

Equation of the line PQ is 3x+2y-5=0 write the slope of the line PQ
2) equation of the line AB is 4x-6y=7 find the y-intercept of line AB
SOLVE ANY 1 IF YOU CAN

Answer 1

Hi,

1) Compare Equation PQ.

3x+2y-5 =0 with ax+by+c=0

a = 3 , b= 2 , c = -5

Slope of a line ax + by + c =0 is

m.

m = ( -a/ b )

m = ( - 3/2 )

Therefore slope of the line PQ is

m = ( -3/2 )

2 )To find y-intercept of the line put

x= 0 in the given equation.


Equation of the line AB is

4x - 6y = 7

Put x= 0 in above equation ,

4×0-6y =7

-6y = 7

y = ( -7/6 )

Therefore,

Y-intercept of AB is ( -7/6 )

I hope this helps you.
