Find the equation of a line parallel to a y = -½x + 7, and goes through (6, 3).

Answer 1

y=-x/2 + b plug in (6,3) to solve for b, the y intercept

3=-6/2 + b

b = 3+6/2 = 6

y=-x/2 + 6 or

x+2y = 12 is the parallel line through (6,3)

parallel lines have the same slope. the slope is the coefficient of the x term when the equation is solved for y
