a linear function f models a relationship in which the dependent variable decreases 3 units for every 2 units the independent variable increases. The value of the function at 0 is 5. find the slope, y-intercept, and x-intercept

f(x)  is y     y is the dependent variable....it depends on the value of 'x'

f(x) = y = mx + b     m is the slope   b is the y intercept (this occurs when x = 0....this is th value on the y axis when x = 0)

f(x) = y = -3/2 x + 5           slope is   rise / run     the Q tells you the value rises -3  for a run of 2     slope = -3/2

 

Summary:  slope  -3/2   y intercept (put in x=0) = 5     x intercept (put in y = 0) = 10/3
