Answer
The equation of the line in point-slope form is
.
Solution
To write the equation of a line in point-slope form, we use the formula:
where
is a point on the line and
is the slope.
Given:
- The point
- The slope
Now, we can substitute these values into the point-slope formula:
-
Substitute
and : -
Simplify the equation:
Thus, the equation of the line in point-slope form is:

Extra Insights
To write the equation of the line in point-slope form, you can use the formula
, where
is the slope and
is the point the line passes through. Here, with a slope of
and passing through the point
, the equation becomes:
This captures the essence of the line through your specified point while using your given slope!
When writing the equation, it’s important to ensure the proper signs are used. Common mistakes include incorrectly substituting the point coordinates or misapplying the slope value. Always double-check that you apply the slope to
and not
or the corresponding
value in the process to avoid errors.
