The equation is .
First find the y-intercept.
\The y-intercept is the value of y, when x = 0.
\ (Substitute x = 0 in original equation)
(Zero product property:
)
The y-intercept is 12.
The co-ordinate point is (0, 12)
Next find the x-intercept.
\The x-intercept is the value of x, when y = 0.
\ (Substitute y = 0 in original equation)
(Add 12 to each side)
(Apply additive inverse property:
)
(Multiply each side by 5)
(Cancel common terms)
(Multiply:
)
(Divide each side by 3)
(Cancel common terms)
x = 20 (Divide: )
The x-intercept is 20.
\The co-ordinate point is (20, 0)
Use these ordered pairs to graph the equation.
\1. Draw a coordinate plane.
\2. Plot the points.
\3. Draw a line through these points.
\The x-intercept is and y-intercept is 1.2.
