Theequation of line CD passes through points
and
in standard form is
and it matches with
.
Further explanation:
It is given that a line passes through points
and
.
The slope of a line passes through points
and
is calculated as follows:
Here, the slope of a line is denoted as
and points are
and
.
Substitute
for
,
for
,
for
and
for
in equation (1) to obtain the slope of a line that passes through points
and
.
Therefore, the slope is
.
The point-slope form of the equation of a line with slope
passes through point
is represented as follows:
Substitute for
,
for
and
for
in equation (2) to obtain the equation of line.
Further simplify the above equation.
Therefore the equation of line CD is
.
Now, the four options are given below.
From above data, it is observed that OPTION Bmatches with the obtained solution
.
Thus, theequation of line CD passes through points
and
in standard form is
and it matches with
.
