Find the equation for the line that passes through the point (1,−4) and that is parallel to the line with the equation y=4.
diamong [38]

Answer:

y = -4.

Step-by-step explanation:

The line with equation y = 4 is a horizontal line on the coordinate plane which passes through the y-axis at y = the point (0, 4).

The other line parallel to this must also be horizontal and , as it passes through the point (1 , -4), must also pass through the y-axis at  ( 0, -4). The equation of this line is y = -4.
