Question

fund the equation of a line which passes through (2,7)and whoose y-intercept is 3​

Answer 1

Answer:

Let the equaLet the equation of the line be

a

x

+

b

y

=1 ..........(i)

when a and b are the x and y intercepts on the axes respectively.

The line passes through (2,7) and b=3 ....(given).

Substituting x=2, y=7, b=3 in equation (i), we have

a

2

3

7

=1

⇒a=−

3

On putting a=−
