Answer:
The slope of the line is -3
Step-by-step explanation:
Slope formula:
m = y₂ - y₁ / x₂ - x₁
Get any two points:
(-2, 4) and (-1, 1)
Solve:
m = 1 - 4 / -1 - (-2)
m = -3 / -1 + 2
m = -3 / 1
m = -3
Check for the third point just in case.
Two points:
(-1, 1) and (1 , -5)
Solve:
-3 = -5 - 1 / 1 - (-1)
-3 = -6 / 1 + 1
-3 = -6 / 2
-3 = -3
So -3 is the legit slope of the three collinear points.
Answer:
Trent has at least 30 cubes.
Step-by-step explanation:
This is because the lowest common multiple of both 5 and 6 is 30. In order for you to get fractions with those denominators, there would have to be a total number in which they share the multiple.
Answer:
2
Step-by-step explanation:
The slope of a line is rise/run.
First, you must choose any two points on the line.
Rise is how many spaces a line moves upward or downward from one point to another.
The run is how many spaces a line moves left or right from one point to another.
It is given that from point M to point N, the line moves up 4 spaces and runs to the right 2 spaces.
- 4 = rise
- 2 = run
- Slope = 4/2, which can be simplified to 2, because 4 divided by 2 is 2.

Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to
where
y is the balance in the saving account
x is the number of years
a is the initial amount
r is the percent rate of change
we have
substitute
For x= 1 year
