Question

Which shows a graph of a linear equation in standard form Ax + By = C, where A = 0, B is positive, and C is negative?

A coordinate plane with a vertical line passing through (1, negative 4), (1, 0) and (1, 4).

A coordinate plane with a vertical line passing through (negative 2, negative 4), (negative 2, 0) and (negative 2, 4).

A coordinate plane with a horizontal line passing through (negative 4, 4), (0, 4) and (negative 4, 4).

A coordinate plane with a horizontal line passing through (negative 4, negative 3), (0, negative 3) and (4, negative 3).

Answer 1

The fourth graph. With A = 0 the equation is By = C → y = C/B, and since B > 0 and C < 0 this is a horizontal line with negative y-value (the line y = −3).
