Question

How to rewrite the this as f(x)=mx+b

28x=7y-14

Answer 1

add \(14\) to both sides, then divide by \(7\) and tell me what you get

Answer 2

or wait for the answer....?

Answer 3

Well this is the form called y-intercept form, y=mx+b, where ity is being denoted as a function f(x)=mx+b

Get y by itself.

Add 14 to both sides to get 28x+14=7y... reverse this around to look better

7y = 28x + 14

Divide all terms by 7 to get

y = 28/7 + 2

Answer 4

Replace y with f(x)

f(x) = (28/7) + 2

Answer 5

I think @Cosmichaotic means \(f(x) = \frac{28}{7}x+2=4x+2\)

so \(f(x) = 4x+2\)

Answer 6

@zzr0ck3r 's suggestion/correction, f(x)=4x+2 is the final form, correct.

Answer 7

can you give me proper procedure how to put that 14 >.<

Answer 8

\[28x=7y-14\]\[28x+(-28x)+7y=-28x-14\]\[\frac{ 7y }{ 7}=\frac{ -28-14 }{ 7}\]
y=-4x-2
