X = 2
y = 8 , Brainliest me please.
ANSWER
B. f(x) = 3x - 8
EXPLANATION
We have the graph of a straight line given and we need to find the function that it represents.
A linear function is generally given as:
f(x) = mx + c
where m = slope
c = y intercept
So, we need to identify the slope and y intercept.
The y intercept is the point where the graph touches the y axis. From the graph, the y intercept is:
c = -8
Now, to find the slope, we use the formula:
where (x1, y1) and (x2, y2) are two points that lie on the graph.
Let us use the given points:
(0, -8) and (1, -5)
Therefore:
Therefore, the equation of the line is:
f(x) = 3x - 8

Answer: The debt in 1999 is estimated to be 370.5 billions.
Step-by-step explanation:
Since we have given that
Amount the outstanding balance on a particular charge card in 1966 = $156
Amount the outstanding balance on a particular charge card in 2002 = $390
Let the number of year be x
and let the amount of outstanding balance be y
As we know the formula for "Slope ":
Here is the coordinates :(1966,156) and (2002,390)
now, we know the formula for "Equation of line":
Hence, the debt in 1999 is estimated to be 370.5 billions.
