Exercise 26 Page 205

a Equations in slope-intercept form follow a certain format.

y = m x + b

In this format

m

is the slope and

b

is the

y -

intercept. The line has a slope of

- \frac{2}{3}

which means that we can substitute

m = - \frac{2}{3} .

b Think of the point where the graph of an equation crosses the

x -

axis. The

y -

value of that

(x, y)

coordinate pair is equal to

0,

and the

x -

value is the

x -

intercept.
