Answer:
Point-slope equation of this line:
.
Step-by-step explanation:
The equation for a line in a cartesian plane can take multiple forms. This question gives
- a point on the line, and
- the slope of the line.
The point-slope form will the most appropriate.
What is the point-slope form equation of a line ?
In general,
,
where
is the x-coordinate of the given point on the line,
is the y-coordinate of the given point on the line, and
is the slope or gradient of the line.
In other words, the point on the line.
For this line,
- The point is
, where
and
.
- Gradient of the line
.
Thus the equation for this line:
.
