Question

If a line passes through the points (-5, -4) and (3, -1), the equation of the line is y + 4 = 3/8(x + _____).

Answer 1

As you can see that it's +4 with y. so it means that they used the first cordinate. Coz it's -4 over there. (as we change it's sign when we insert in the equation; -(-4) = +4.)
so in the blank we will write 5.
