**Problem: Write parametric equations of a
line through (7, 5) with slope of 3. Graph the line using your
equations. **

**where (7,5) is the time = 0 point and (1,
3) represents the rate of change as time increases.**

**Then,**

**and**

**These parametric equations would yield the
following points:**

The Equations

**Instead of using the vector approach to
this problem, let's try using the point-slope formula.**

**Having found the line, we now write parametric
equations of this line:**
