Question

Write the equation of the line that passes through (-3,9) and is parallel to y = -2x + 5

Answer 1

y = -2x +3

Explanation:

Parallel lines always have the same slope

To insert the point, use the slope intercept formula: y =mx+b

insert y (9)

insert x (-3)

insert the slope -2

9 = (-2)(-3) + b

9 = 6+b

subtract 6 from both sides

3 = b
