50 points answer quick which function has the greatest value when x is equal to 0? a. x y 3 3 4 6 5 9 b. y = 4x – 7 c. 12x + 6y = 30 d. a linear function that goes through point 1, negative 1 and point 0, 4

C. 12x + 6y = 30

Step-by-step explanation:

A. x  345  

   y   3    6     9

We need to make and equation

slope = (y2-y1)/(x2-x1)

    = (9-3)/(5-3)

    6/2

  3

The slope is 3

Using point slope form

y-y1 = m(x-x1)

y-3  = 3(x-3)

Distribute

y-3 = 3x-9

Add 3 to each side

y = 3x-9+3

y = 3x-6

Let x=0

y = 0-6

y = -6

B. y = 4x – 7

Let x = 0

y = 0-7

y = -7

C. 12x + 6y = 30

Let x = 0

12(0) + 6 y = 30

6y = 30

Divide by 6

6y/6 = 30/6

y =5

D. A linear function that goes through point 1, negative 1 and point 0, 4

The point ((0,4) says when x=0   y=4

y =4

y=5  is the max so the answer is C
