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
