Answer:
y = 1/2x - 6
Step-by-step explanation:
y2 - y1 / x2 - x1
-3 - (-5) / 6 - 2
2/4
= 1/2
y = 1/2x + b
-3 = 1/2(6) + b
-3 = 3 + b
-6 = b
It kind of looks like your missing something in you problem. But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3. So f(4.5) = 3. Most of the time though f(x) means a function of x, so there is an x in the problem. For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
