Question

25.
Find the equation of a line containing the
point A(3, 4) and making equal intercepts
on the co-ordinate axes.​

Answer 1

Answer:

X+y=7

Step-by-step explanation:

equation of yah line having a a, b are intercepts

$\frac{x}{a} + \frac{y}{b} = 1$

here It is making equal intercepts so a = b

$\frac{x}{a} + \frac{y}{a } = 1$

.passing through(3,4)

$\frac{3}{a} + \frac{4}{a} = 1$

$\frac{7}{a} = 1$

a=7

$\frac{x}{7} + \frac{y}{7} = 1$

$\frac{x + y}{7} = 1$

so X+y=7 is our required equation
