Answer 1

start by finding the slope of given line

Answer 2

whats the slope of given equation ?

Answer 3

@ganeshie8 -7/9?

Answer 4

check again

Answer 5

when u send y term to other side, it becomes positive right ?

Answer 6

7x - 9y + 10 =0

7x + 10 = 9y

Answer 7

so slope of given line is ?
