Abstract
The graph of a linear function is a straight line. Its slope a equals the rate of change of y relative to x. A unit change in x produces a change a in y: The ratio-the change in F to a change h in x—equals a: We learned all of this in Chapter 1, Section 2.
$$ y = F\left( x\right)= ax + b $$
$$ F\left( {x + 1} \right) - F\left( x \right) = a\left( {x + 1} \right) - ax = a $$
$$ \frac{{F\left( {x + h} \right) - F\left( x \right)}}{h} = \frac{{a\left( {x + h} \right) - a(x)}}{h} = \frac{{ah}}{h} = a $$
