Question

Write the equation of a line, in general form , that has an slope of zero and a y-intercept of (0, 4).

A.) x - 4y = 0
B.) y - 4 = 0
C.) x - y = 4
D.) x - 4 = 0

Answer 1

B) y- 4 = 0

Explanation:

The general form of an equation of a line:

Ax + By + C = 0

We have the line with a slope = 0. Therefore it's a horizontal line.

The equation of a horizontal line:

y = a

The line passes through points with coordinates in form (x, a).

We have the point (0, 4). Therefore the equation of this line is y = 4.

Convert to the general form:

y = 4 subtract 4 from both sides

y - 4 = 0

Answer 2

the solution is b

Explanation:

y - 4 = 0(x-0)

y -4=0
