Question

Write the equation of the line passing through (2,0) and (0,-5)​

Answer 1

y=5/2x+2

Explanation:

To get the slope,

(-5-0) /(0-2)=-5/-2=5/2

Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way

(0,2)(x,y)

y-2/x-0=5/2

Cross multiplication,2(y-2)=5(x-0)

2y-4=5x-0

2y=5x-0+4

2y=5x +4

Divide both sides by 2 to get

y=5/2x+2.
