Answer:
y = 
Step-by-step explanation:
The equation used to find the equation for a line with two intercepts is called point slope form.
, where
and
are the intercept points and m is the slope.
However, we need the slope to use this formula.
Use 
m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}



y - ( -7 ) = m ( x - ( 4 ) )
y - ( -7 ) = -7/4 ( x - ( 4 ) )
y + 7 = -7/4 ( x + 4 )
y + 7 = 
y + 7 = 
y + 7 = 
y + 7 =
- 7
y = 
Answer:
C
Step-by-step explanation:
The rubber exercise ball is a sphere
the volume of a sphere= 4/3*pi*r3
where r = the radius of the sphere.
from the diagram, the radius = 4.5inches
Therefore, volume of the rubber ball = 4/3*pi*4.5^3 = 381.51 cubic inches
Answer:
y =
x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m =
, then
y =
x +c ← is the partial equation
To find c substitute (- 4, - 3) into the partial equation
- 3 = - 3 + c ⇒ c = - 3 + 3 = 0
y =
x ← equation of line
4 and -2.5
You can get this by first factoring the equation.
(2x + 5)(x - 4)
Then set both equal to zero and solve individually.
