How much money at 12 weeks?

1). 330
2). 290
3). 360

To answer this question, you need to write a linear equation (because the graph is a visibly straight line) that models this situation, then plug in 12.

The general format for a linear equation is y=mx+b, where m is the slope and b is the y intercept.  The y intercept of a line is where it crosses the y axis; for this line, it crosses the y axis at (0, 0) so the y intercept is 0.

To find the slope, use the slope equation: (y2-y1)/(x2-x1).  For y1, y2, x1, and x2, just pick any two points on the line.  We will use (1, 30) and (2, 60):

(60-30)/(2-1)

30/1

30

The line is y=30x.

Plug in 12 for x:

y=30(12)

y=360

3). 360

Hope this helps!!

the answer is 3/2 and for decimal: 1.5

-lavira: )

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
