Define Point-Slope Form:
Point-slope form is
y
−
y
1
=
m
(
x
−
x
1
)
y - y_1 = m(x - x_1)
y
−
y
1
=
m
(
x
−
x
1
)
, where
m
m
m
is the slope and
(
x
1
,
y
1
)
(x_1, y_1)
(
x
1
,
y
1
)
is the point the line passes through.
Identify Slope and Point:
We know the slope
m
m
m
is
9
9
9
and the point is
(
9
,
9
)
(9,9)
(
9
,
9
)
, so we plug these values into the point-slope form.
Substitute Values into Formula:
y
−
9
=
9
(
x
−
9
)
y - 9 = 9(x - 9)
y
−
9
=
9
(
x
−
9
)
is the equation in point-slope form.
