Find an equation for the line with the given properties.
-Parallel to the line y = -3x; containing the point (7, 2)
A) y = -3x - 23
B) y = -3x
C) y - 2 = -3x - 7
D) y = -3x + 23

Question

A line parallel to y = -3x has the same slope, which is -3. Using the point (7, 2) in the point-slope form y - y1 = m(x - x1), we get y - 2 = -3(x - 7). Simplifying gives y = -3x + 21 + 2, which is y = -3x + 23.
