Step-by-step explanation:
The given parametric equations are;
and
,
.
We can graph this by plotting some few points within the given range or eliminate the parameter to identify the type of curve.
Plotting points;
When
,
and 
This gives the point (-4,3).
When 
and 
This gives the point (0,5).
When 
and 
This gives the point (6,8).
We plot these points and draw a straight line through them.
Eliminating the parameter.


Make t the subject in the second equation;

Substitute into the first equation;

This implies that;


This is an equation of a straight line with slope
and y-intercept 5 on the interval

C.21 ft x 48 ft
because you multiply 7 by 3 and 12 by 3 and that is what it is
