Observe the graph; the line is passing through (4, 3) and (7, -2). \"\" \"\" The line equation in slope-intercept form is \"\", where m is the slope and b is

\

 the y-intercept.

\

 First find the slope (m).

\

Slope formulae is \"\"

\

\"\"                           (Replace \"\" with 4, 3, 7 and -2)

\

\"\"                              (Subtract: \"\" )

\

\"\"                                (Subtract: \"\")

\

Slope is \"\"\"\"

\

Next find the y-intercept (b).

\

\"\"                         (Substitute \"\" for m)

\

\"\"                      (Substitute 4, 3 for x and y)

\

\"\"                        (Multiply: \"\")

\

\"\"     (Add \"\" to each side)

\

\"\"     (Apply Commutative property: \"\")

\

\"\"                      (Apply Additive inverse property: \"\")

\

\"\"                            (Apply Additive identity property: \"\")

\

\"\"                                 (Add:\"\")\"\"

\

 Substitute \"\" for m and \"\" for bin the Slope-intercept form equation

\

\"\"

\

 \"\"

\

The equation in slope-intercept form is \"\".
