Question

An equation for the line that passes through the points (6, -6) and (-4, 6) .

Answer 1

Answer:

y = -6/5x + 6/5

Step-by-step explanation:

equation formula is y = mx + b

m = slope

slope = change in y / change in x = (6 - -6) / (-4 - 6) = 12/-10 = -6/5

So m = -6/5

Now to find b, substitute one of the coordinates. Let's use (6, -6)

y = -6/5x + b

-6 = -6/5(6) + b

-6 = -36/5 + b

6/5 = b

So equation is y = -6/5x + 6/5
