Question

For which values of a, b, and c will Ax+ By=C be a horizontal line through the point (-4,2)

Answer 1

A = 0, B = 1 and C = 2

Explanation:

The slope of a horizonal line is zero.

y = mx + b Use the slope intercept form with m = 0 and point (-4, 2).

2 = 0(-4) + b Solve for "b"

2 = 0 + b

2 = b

The equation in slope intercept form is y = 0x + 2 ; y = 2.

The equation in standard form: Ax + By = C has the value 0x + y = 2
