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)
(Multiply:
)
(Apply additive identity property:
)
\
(Multiply each side by negative one)
(Product of two same signs is positive)
(Product of two diffirent signs is negative)
The y-intercept is , so the graph intersects the y-axis at
.
Next find the x-intercept.
\The x-intercept is the value of x, when y = 0.
\ (Substitute y = 0 in original equation)
(Additive identity property:
)
(Divide each side by 5)
(Cancel common terms) \ \
The x-intercept is
,so the graph intersects the x-axis at
.
Graph Using Intercepts:
\Use these ordered pairs to graph the equation.
\1. Draw a coordinate plane.
\2. Plot the points.
\3. Draw a line through these points.
\
x-intercept is and y-intercept is
.
