Question

A coordinate plane with a line passing through the points (0, negative 1, 0) and (4, 0).
What is the equation of the graphed line written in standard form?

x – 4y = 4
x + 4y = 4

Answer 1

First find the slope: m = (0 - (−1)) / (4 - 0) = 1/4.

Point-slope with (0, −1): y + 1 = (1/4)x → 4y + 4 = x → x − 4y = 4.

So the correct equation is x − 4y = 4.
