Write an equation for a line parallel to g(x) = 3x − 1 and passing through the point (4, 9)

y=3x-3

Step-by-step explanation:

To find a line that is parallel to the function, we know that the slope must stay the same. Parallel lines NEVER cross. This means the slope MUST be the same. All we have to change is the y-intercept. We can use the given point to find the correct y-intercept.

y=3x+b                                     [plug in (4,9)]

9=3(4)+b                                 [multiply]

9=12+b                                     [subtract both sides by 12]

b=-3    

Now, we know that the y-intercept is -3, we can put together our equation. y=3x-3

the answer is 99.
