Question

Which is the equation of a line thag passes through the points (1,-1) and (3,-5)

Answer 1

The question is incomplete other wise it is really easy to solve if you now how to make the line of equation. As we know the formula to calculate the line of equation is y - y1 = m (x - x1)

Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.

And the formula for slope is as we know is m = y2 - y1 divided by x2 - x1.

Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.
