Complete the equation of the line through (2,-2) and (4,1).

scoundrel [369]

Slope formula : (y2 - y1) / (x2 - x1)
(2,-2)....x1 = 2 and y1 = -2
(4,1)...x2 = 4 and y2 = 1
now we sub into the slope formula and solve for the slope
slope = (1 - (-2) / (4 - 2) = (1 + 2) / 2 = 3/2

now we use y = mx + b
slope(m) = 3/2
use either of ur points....(4,1)...x = 4 and y = 1
now sub into y = mx + b formula and find b, the y int
1 = 3/2(4) + b
1 = 6 + b
1 - 6 = b
-5 = b

so ur equation is : y = 3/2x - 5 <==

"The length of a rectangle is 5/2 units greater than its width"

'greater' here means multiplication, 5/2 units greater or 5/2 times more. So we know that the length is $\sf\dfrac{5}{2}w$ .

Perimeter of a rectangle is:

$\sf P=l+w$

Plug in our value for the length:

$\sf P=\boxed{\sf \dfrac{5}{2}w+w}$

Which undefined geometric term is described as an infinite set of points that has length but not width?

Ivahew [28]

<span>The correct answer is line.

Explanation:
A line contains an infinite number of points, but since each point has no width or length to speak of, there is no width to a line. Additionally, it has infinite length since there is an infinite number of points included in it.</span>
