Question

Vladimir says that the equation of the line that passes through points (negative 5, negative 3) and (10, 9) is y = four-fifths x + 1. Robyn says that the line passes through the points (negative 10, negative 7) and (negative 15, negative 11). Who is correct?
only Vladimir
only Robyn
both Vladimir and Robyn
neither Vladimir nor Robyn

Answer 2

Both Vladimir and Robyn are correct. Then the correct option is C.

What is the equation of a line passing through two points?

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

$\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)$

Vladimir says that the equation of the line that passes through points (-5, -3) and (10, 9) is y = (4/5) x + 1.

Robyn says that the line passes through the points (-10, -7) and (-15, -11).

Then the equation of the line will be

y + 7 = [(-11 + 7) / (-15 + 10)] (x + 10)

y + 7 = (4/5)x + 8

     y = (4/5)x + 1

Both Vladimir and Robyn are correct.

Then the correct option is C.
