As we go from (-4, 2) to (6, -3), x (the "run") increases by 10 and y (the "rise") decreases by 5. Thus, the slope of the line connecting these two points is m = rise / run = m = -5/10, or m = -1/2.
We adapt the slope-intercept form as follows: y = mx + b becomes
2 = (-1/2)(-4) + b, or
2 = 2 + b. Therefore, b must be 0. The desired eequation is y = (-1/2)x.
To figure this out, divide the annual salary by the months in a year. 29,500/12=2458.33 Now divide that by half of the amount of weeks in month 2458.33/1.5=1638.88 So the answer is none of the above.
