Answer:
ok so first we have to convert this into y intercept
4x-y=4
-4x
-y=-4x+4
*-1
y=4x-4
so the y intercept is -4
Hope This Helps!!!
Answer:
f(x) = - 3x + 4
Step-by-step explanation:
Note that y = f(x)
Given
9x + 3y = 12 ← Rearrange making y the subject
Subtract 9x from both sides
3y = - 9x + 12 ( divide all term by 3 )
y = - 3x + 4, thus
f(x) = - 3x + 4
