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:
)
(Multiply each side by negative one)
(Product two same signs is positive)
(Product two different signs is negative)
The y-intercept is .
Next find the x-intercept.
\The x-intercept is the value of x, when y = 0.
\ (Substitute y = 0 in original equation)
(Apply additive identity property:
)
(Divide each side by 7)
(Cancel common terms)
(Divide:
)
The x-intercept is .
x-intercept is and y-intercept is
.
