**Answer:**

See below.

**Step-by-step explanation:**

f(3) means the y-coordinate of the point that has x-coordinate 3.

To find f(3) using a graph of f(x).

Look up x = 3 on the x axis. If the function passes through that point on the x-axis, then f(3) is 0. If the function does not pass through that point, then go up or down till you intersect the function. Draw a horizontal segment left to the y-axis and read the point on the y-axis that the horizontal segment intersects. That is what f(3) is equal to.

2y= 7x+18

6x+ 3(7x+18)=0

6x+21x+54=0

27x=-54

x=-2

6(-2)+6y=0

6y=12

y=2

6(-2)+6(2)=0

-12+12=0 True

-7(-2)+2(2)=18

14+4=18 True
