Question

Write the equation of the line that passes through the given point and is parallel to the given line:

(2,7); 3x - y = 5

Answer 1

3x -y = -1

Explanation:

The parallel line can have the same x- and y-coefficients. It will have a different constant. The constant can be found using the x- and y-values of the given point to make sure they satisfy the equation.

3x -y = 3(2) -(7) = -1

The equation of the line is ...

3x -y = -1
