The given line is .
Above line is slope - intercept form .
So, given line has a slope of() =
1.
So, a line parallel to it has a slope of .
Because you know the slope and a point on the line,
\Use point - slope form to write an equation of the line.
Let =
and slope(
) =
1.
(Substitute 1 for
, 7 for
and
=
1)
Rewrite in slope - intercept form .
(Apply distributive property:
)
(Multiply:
)
Apply addition property of equality: If a = b then a + c = b + c.
\ (Add 1 to each side)
(Apply additive inverse property:
)
(Apply additive identity property:
)
(Add:
)
Check:
\To check the solution substitute =
in
.
(Product of different signs is negative)
(Add:
)
The equation satisfies the condition.
\So,The equation of the line is .
The equation of the line is .
