Question

Write the equation of the line that is parallel to the graph of 3x-y=5 whose y-intercept is (0,4)

Answer 1

3x -y = -4

Explanation:

You want the equation of the line parallel to 3x-y=5 through point (0, 4).

Parallel line

The equation for the parallel will differ only in the constant. To find the new constant, use the given point coordinates for x and y.

3x -y = 3(0) -(4) = -4

The equation of the line is ...

3x -y = -4
