Find an equation of the line through (2,5) and parallel to y=4x-4. write the equation using the function notation.

Question

ajprincess · Answer

Let f(x)=y, where
y=mx+c be the equation of the line.
m-slope
c-y_intercept
For parallel lines slopes are equal.
Slope of the given line=4.
So slope m of the required line=4
y=4x+c
Nw plug in 2 in place of x and 5 in place of y to find c. 
Can u find it @NeedSomehelpplz?

y=8+5 ?

anonymous · Answer

y=8x+5 ?

ajprincess · Answer

hmm no.
Let us find c first by substituting the values of x nd y in
y=4x+c
5=4*2+c
c=8-5
 =3
Is this clear @Needsomehelpplz?

Thanks, I think I've got it.

ajprincess · Answer

Nw ur equation will be 
y=4x+3
In function form
f(x)=4x+3
