Answer: 3580.50
Step-by-step explanation:
The answer is y = 2x - 3. Because you'll first start a point -3. Now 2x would change and add an invisible on making it 2/1. Then from point -3. You'll rise up 2 units and run 1 unit to the right. Showing exactly in the graph.
Answer:
$400
OR 
Step-by-step explanation:
$400 stays the same, 72 cents is 72/100. Simplify and voila
If you recall y=mx+b, the slope-intercept form of a linear equation, the slope, m, is the rate of change of the equation, and the y-intercept is b.
When switching to function notation, we simply swap y for f(x), and if we start at x=0 and graph in the positive x direction, we've started at whatever initial value exists (the y-intercept value).
Simply: F(x) = 2/3 x + 4
