Example Question #111 : Coordinate Geometry
Find the equation of a line passing through the points
and .None of these.
To find the equation of a line passing through these points we must find a line with that same slope. Start by finding the slope between the two points and then use the point slope equation to find the equation of the line.
slope:
Now use the point slope equation:
*make sure you use the SAME coordinate pair when substituting x and y into the point slope equation.
Example Question #112 : Lines
Find the equation of a line that goes through the points
and .
Recall that the slope-intercept form of a line:
,
where
and .First, find the slope of the line by using the following formula:
Next, find the y-intercept of the line by plugging in
of the points into the semi-completed formula.
Plugging in
yields the following:
Solve for
.
The equation of the line is then
.
