Aline passing through the points (6, –2) and (–2, 4).

-6x - 8y + 20 = 0

Step-by-step explanation:

If you have two points (x₁; y₁) and (x₂; y₂), you can use the formula to find the equation of a straight line:

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
