Find an equation of the line through (1,5) and parallel to y=4x+5Write the equation using function notation

Question

Im having trouble creating an equation. I can do y=4x+1/5 but that's not the correct notation

Answer 1

y = 4x + 5, the slope is 4 as is the line parallel

y = 4x + b

5 = 4(1) + b, substitute coordinates

1 = b

f(x) = 4x + 1
