Problem: Write parametric equations of a
line through (7, 5) with slope of 3. Graph the line using your
where (7,5) is the time = 0 point and (1, 3) represents the rate of change as time increases.
These parametric equations would yield the following points:
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:
To use this strategy in a word problem,
