Answer:

y = -4x +2

Step-by-step explanation:

The equation you're writing is in slope-intercept form. The coefficient of x is the slope, which is the "rise"/"run" of the line.

Here, to get from the left point to the right point, you must go down 4 units (rise=-4) and 1 unit to the right (run=1). So, the slope is ...

m = rise/run = -4/1 = -4

The constant in the equation is the y-intercept: the y-coordinate of the point where the line crosses the y-axis. That point is marked as (0, 2), so its y-coordinate is 2.

The equation for the line is ...

y = -4x +2

With a ruler, Diamond determines the diameter of a golf ball to be 4.2 centimeters (a radius of 2.1 cm) and the diameter of a pr

Troyanec [42]

Answer:

Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball

Step-by-step explanation:

we know that

The volume of a sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

where

r is the radius

step 1

Find the volume of the golf ball

we have

$r=2.1\ cm\\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(2.1)^{3}=38.77\ cm^3$

step 2

Find the volume of the the softball

we have

$r=4.2\ cm\\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(4.2)^{3}=310.18\ cm^3$

step 3

Find the ratio of volumes

Divide the volume of the softball by the volume of the golf ball

$\frac{310.18}{38.77}=8$

That means

Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball
