Question

_ of the following is the line joining the point of intersection y-x+7=0and y+2x-2=0and origin
​

Answer 1

Solving equations
y - x = - 7
y + 2x = 2
On subtract these 2 equations
-3x = -9
x = 3

Put x = 3 in equation (1)
y - 3 = - 7
y = -4
So, point of intersection is (3, - 4).

So equation of line joining (3, -4) and (0, 0) using two point form is
y - 0 = (-4-0)/(3-0) (x - 0)
y = -4/3 x
3y = -4x
4x + 3y = 0

Answer 2
