The line equation in slope-intercept form is y = mx + b, where m is the slope

and b is the y-intercept.

Identify the slope. The slope is . \

Find the y-intercept value by substituting the slope and the coordinates of the given

point in the equation.

y = mx + b                            (Slope-intercept form line equation)

            (Substitute for m, 8 for x, and –4 for y)

                   (Multiply: )

                        (Divide: )

            (Add 6 on each side)

            (Commutative property: a + b = b + a)

                            (Additive inverse property: )

                                     (Add: )

\

Now substitute the values of slope ‘m’ and y-intercept ‘b’ in slope intercept

form line equation

y = mx + b                            (Slope-intercept form line equation)

               (Substitute for m and 2 for b)

                       (Product of two different signs is negative)

 The equation of the line that passes through the point (8, –4) and

has a slope of is .
