Question

what will be the new equation of the straight line 3x+4y=15, if the origin gets shifted to (1.-3)
​

Answer 1

Answer:

3x +4y = 6

Explanation:

3(x-1) +4(y-(-3)) = 15

3x - 3 + 4y + 4*3 =15

3x + 4y = 15 - 12 + 3

3x +4y = 6

Answer 2

$\color{blue}{♥︎ Answer: ♥︎}$

3x + 4y = 6

Step-by-step explanation:

Original equation => 3x + 4y = 15

Points: (1,-3)

3(x - 1) + 4(y + 3) = 15

3x - 3 + 4y + 12 = 15

3x + 4y = 15 - 9 ;[-3 + 12 = 9]

∴ 3x + 4y = 6
