(1,0)(0,9)

Question

Determine an equation of a line in various from given two points

 

Answer 1

The two point form of the General First Degree Equation Formula is applied well here..

Recall y = mx + b.

Now, y - y₁ = ((y₂ - y₁)/(x₂ - x1))(x - x₁)

The derivation and substitution with check is left for the student, place "1" in for example in for every x₁, and "0" where it respectively belongs in the x₂ and y₁ parameters. Lastly, with "9" should go where that pattern here follows.

 

ans. The equation of a line passing through the two given points in the real plane, invariant with slope here following

is: y = -9x + 9
