Question

Find the point-slope equation for the line that passes through the points (5, 19) and (-5, -1). Use the first point in your equation y - [?] = [](x - [ ]) = ​

Answer 1

Answer:

$m = \frac{y_ 2 -y_ 1}{x_ 2 -x_ 1 } \\ = \frac{ - 1 - 19}{ - 5 - 5} = \frac{ - 2 0 }{ - 10} \\ \therefore \: m = 2 \\ y + 1 = 2(x + 5)$
