2. A line has an x-intercept of 2 and a y-intercept of 5. What is the slope<br> of the line?

Blizzard [7]

Answer:

-5/2

Step-by-step explanation:

Use slope formula:

Given 2 points (x1, y1) and (x2, y2) Slope is

y2-y1/x2-x1

The x intercept is 2, the point would be (2,0)

The y intercept is 5, the point would be (0,5)

So you can do (5-0)/(0-2) which is 5/-2 which then would be -5/2

Answer:

28.25 square units

Step-by-step explanation:

A circumference of the circle is

$C=2\pi r,$

where r is the radius of the circle.

So,

$18.84=2\pi r\\ \\r=\dfrac{18.84}{2\pi}=\dfrac{9.42}{\pi}\ cm$

The area of the circle is

$A=\pi r^2$

Substitute the value of the radius:

$A=\pi \cdot \left(\dfrac{9.42}{\pi}\right)^2=\dfrac{9.42^2}{\pi}\approx 28.25\ un^2$
