Find an equation of the line through (1,8) and parallel to y = 4x + 3. Write the equation using function notation.

f (x) =

f (x) = 4x + 4

Step-by-step explanation:

When a line is parallel to another line, the slopes are always equal. Therefore, the coefficient for x has to be four. If you multiply the y-coordinate by 4, you get 4. To get 8, you have to add four, so the equation is simply f (x) = 4x+4.
