Question

Find equation of the line passing through points
(1, -1) and (3,5)
​

Answer 1

The equation of the line passing through points (1,-1) and (3,5 ) is y-3x+4

Step-by-step explanation:

Given point , (1,-1) and (3,5)

We know that ,when two point (x₁,y₁) (x₂,y₂ )given

then,equation of the line is y-y₁= (y₂-y₁)/(x₂-x₁) *(x-x₁)

So, Given point (1,-1 ) and (3,5)

• => y-(-1) = 5-(-1) / 3-1 * (x-1)

• =>y +1 = 6/2 (x-1)

• => y +1 = 3(x-1)

• => y + 1 = 3x -3

• => y -3x +1+3

• => y -3x +4 is required equation
