Answer:
slope (m)= 1/2
y-intercept: (0, -1)
equation: y=
x-1
Step-by-step explanation:
slope is
=
y-intercept is where the line crosses the vertical axis (y-axis) so its (0, -1)
using point slope form:
y-y1=m(x-x1)
y-(-1)=1/2(x-0)
y+1=1/2x
y=
x-1
Answer: The slope of the line is 
Step-by-step explanation:
The slope of a line can be calculated with the following formula:

Then, given the points
and
, you can identify that:

Knowing these values you can substitute them into the formula for calculate the slope:

Finally, evaluating, you get that the slope of that line is:

Answer:
C
Step-by-step explanation:
The volume (V) of a sphere is calculated using the formula
V =
πr³
If the radius is doubled, that is r = 2r , then
V =
π (2r )³
(2r)³ = 8r³, thus the volume is multiplied by 8
Answer:
(a) 0.6
(b) 0.4
Step-by-step explanation:
If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made
shots.
The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,
making a shot
Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.
