The horizontal distance a projectile travels is represented by

• x

• y

• t

The vertical distance a projectile travels is represented by

• x

• y

• t

Eliminate the parameter.

x= 2+4t and y=-1+6t

• y=(3/2)x - 4

• t=(x-2)/4

• y=x - 4

• y= (2/3)x + 4

Write x = 2t  and y = t² + 3  in rectangular form .

• y = 4x²  + 3
• y = ¼ x² + 3
• y = 4t² + 12
• y = (x - 2)² + 3

Eliminate the parameter. Convert the parametric equation to rectangular. x= t - 1 and y=t² - 2

• y=(x+1)² - 2
• t=x - 1
• x=t - 1
• y=t - 2

Find the point based on the parametric equations. t = 3

x = 1 - 2t

y =4t + 1

• (-5, 13)

• (13, -5)

• (5, 13)

• (13, 5)

Find the ordered pair based on the parametric equations.

t = -2

x = t² - 2

y = -t + 2

• (2, 4)

• (4, 2)

• (-6, 0)

• (0,-6)

Graph the parametric equation x(t) = t² + 5 and y(t) = t² - 4. Which of the following sketches results?

• Linear

• Quadratic

• Quartic

• Square Root
