Question

Find the equation of this line.(2,2) and (0,-4)

Answer 1

To find the equation;

x₁ = 2 y₁ = 2 x₂ = 0 y₂=-4

we will use the formula;

`y-y_1=(y_2-y_1)/(x_2-x_1)(x_{}-x_1)`

substituting the values into the above;

`y-2=(-4-2)/(0-2)(x-2)`

Then, we will go ahead and evaluate;

`y-2\text{ = }(-6)/(-2)(x-2)`

`y-2\text{ =3(x-2)}`

y - 2 = 3x - 6

add 2 to both-side of the equation

y = 3x -6+ 2

y = 3x -4
