Which set of parametric equations describes a line that passes through the points (0,0) and (4,8) ?

A) x=t , y=2t
B) x=2t , y=3t
C) x=2t , y=t
D) x=4t , y=2t

The correct option is A)

Step-by-step explanation:

To find the correct equation we first need to calculate the angular coefficient for the line, with the formula below:

m = (y2 - y1)/(x2 - x1)

m = (8 - 0)/(4 - 0) = 8/4 = 2

Using that we can apply to the equation of the line:

y = m*x + c

Since the line pass through (0,0) c must be equal to 0, so:

y = m*x

y = 2*x

So x must be:

x = t.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
