Answer:

The answer is in attachment

Explanation:

First step finde a function t(x) ⇒ t=x/2;

Now we need to finde the limits of that function:

if t=-2 ⇒ x=-4 and t=3 ⇒ x=6. That means -4≤x≤6

Now replace on y(t) ⇒ y(x)= x/2+5, 4≤x≤6

X = 2t y = t + 5, -2 ≤ t ≤ 3 Can you please graph this-example-1

Answer:

See attachment

Explanation:

The given parametric equations are;


x=2t and
y=t+5,
-2\le t\le 3.

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
t=-2,


x=2(-2)=4 and
y=-2+5=3

This gives the point (-4,3).

When
t=0


x=2(0)=0 and
y=0+5=5

This gives the point (0,5).

When
t=3


x=2(3)=6 and
y=3+5=8

This gives the point (6,8).

We plot these points and draw a straight line through them.

Eliminating the parameter.


x=2t


y=t+5

Make t the subject in the second equation;


t=y-5

Substitute into the first equation;


x=2(y-5)

This implies that;


x=2y-10


y=(1)/(2)x+5

This is an equation of a straight line with slope
(1)/(2) and y-intercept 5 on the interval


-4\le x \le 6

X = 2t y = t + 5, -2 ≤ t ≤ 3 Can you please graph this-example-1
