Answer:

<h2>A plane consists of an infinite set of lines.</h2><h2>A line has one dimension, length. </h2>

Step-by-step explanation:

The choices are

A point in the form (x, y) has two dimensions.
A plane has a definite beginning and end.
A line has one dimension, length.
A point consists of an infinite set of lines.
A plane consists of an infinite set of lines.

In Ecludian geometry, undefined term are the plane, point and line. Becasue these terms are too intuitive, we don't need to demonstrate them, they just exits, they are too primitive to be defined, that's why they are undefined term.

However, there are some characteristics about each term, for example, a line and a plane are infinite, the plane is formed by infinite of lines and the line is formed by infinite set of points. Additionally, a line has one dimension only, because it's formed by infinte set of points, which doesn't have a dimensions as a singular term, but all together form a length.

Therefore, the right answers are C and E.

Answer:

y=2x-2

Step-by-step explanation:

<em>the slope is y/x</em>

the slope is 2 or 2/1

<em>subtract 2 from the y value and 1 from the x value</em>

(3-1,4-2) = (2,2)

<em>keep doing this until you get a 0 in the x value</em>

(2-1,2-2) = (1,0)

<em>1 is your x-intercept</em>

(1-1,0-2) = (0,-2)

-2 is your y intercept.

So now you know your y-intercept and your slope so you can now write your equation.

<em>m=slope, b=y-intercept</em>

m=2, b=-2

<em>substitute into the equation</em>

y=2x-2

Can someone please explain to me how to do this.

Y = x² - 4x + 4
y = 2x - 4

Find intersection of L and C:
x² - 4x + 4 = 2x - 4
x² - 6x + 8 = 0
<span> (x - 2)(x - 4) = 0
x = 2 or x = 4

When x = 2 , y = 2(2) - 4 = 0
When x = 4, y = 2(4) - 4 = 4

Points of intersection = A(2, 0) and B(4, 4)

Find the length of AB:

</span> $
\text {Length of AB}= \sqrt{(4-0)^2 + (4-2)^2} = \sqrt{16 + 4} = \sqrt{20} = 4.47 \text{ units}$
<span>
Answer: 4.47 units
