Question

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

An equation of parallel line is y=___

Answer 1

Explanation:

The slope is in the given line. It is the number in front of the x which is 3.

So far what you have is

y = 3x + b

Now use the point to find b

x = 2

y = 2

Substitute

y = 3*2 + b

2 = 6 + b

2 - 6 = b

b = - 4

y = 3x - 4
