The expression is .
The equation is in slope-intercept form.
\To graph the equation, first graph the .
According to subtraction property of equality: if , then
.
(Subtract 5x from each side)
(Commutative property: a + b = b + a)
(Additive inverse property:
)
(Multiply each side by negative one)
(Product of two same signs is positive)
(Distributive property: a(b
c) = ab
ac)
(Product of two same signs is positive)
First find the y-intercept.
\The y-intercept is the value of y, when x = 0.
\ (Zero product property:
)
(Additive identity property:
)
Next find the x-intercept
\The co-ordinate point is
The x-intercept is the value of x, when y = 0.
\ (Add 35 to each side)
(Cancel common terms)
(Additive identity property:
)
(Divide each side by 5)
(Cancel common terms)
x = 7 (Divide: )
Next find the y-intercept.
\The co-ordinate point is (7, 0)
