What is slope when talking about math
2 answers:
When graphing, its how much you rise and run
thats the formula when u have a graph and the question is asking for the slope.
you chose a point, and go down or up however many times it goes to the next point, and you run to the left however many times it gets you to get to that point.
if the line goes downward the slope is therefore negative, and if the line goes upward, the slope is therefore, positive.
m in math is meant to be slope, so

Answer: 1/3
Step-by-step explanation: In algebra, we use the word <em>slope</em> to describe how steep a line is. Slope can be found using the ratio <em>rise/run</em> between any two points that are on that line.
For the line in the image provided, let's use the points A and B to find its slope. To get from point A to point B on this line, we would rise 1 unit and run 3 units. So the slope of this line or its rise over run is 1/3.
The variable that is used to represent slope is <em>m</em>. So for this line we would say that m = 1/3. It's important to understand that no matter what two points you choose along this line, the slope or rise over run can always be simplified to 1/3.

Step-by-step explanation:
Given the sequence -4,-6,-8..., in order to get sigma notation to represent the sum of the first seven terms of the sequence, we need to first calculate the sum of the first seven terms of the sequence as shown;
The sum of an arithmetic series is expressed as
n is the number of terms
a is the first term of the sequence
d is the common difference
Given parameters
n = 7, a = -4 and d = -6-(-4) = -8-(-6) = -2
Required
Sum of the first seven terms of the sequence
The sum of the nth term of the sequence will be;
The sigma notation will be expressed as . <em>The limit ranges from 1 to 7 since we are to find the sum of the first seven terms of the series.</em>

Step-by-step explanation:
Hello!
x² + 5x + 6
Find two numbers that add up to 5 and multiply to 6. We get:
2, 3
Therefore:
(x + 2)(x + 3)
In the matrix, the first row is exactly twice the second. This implies that the determinant is zero.
If the matrix system has determinant zero, the system has either no solutions or infinite solutions.
However, just like in the matrix, in the constant vector the first term is twice the second. This means that the system has infinite solutions.
In fact, if you write this system in expanded form, you can see that it generates two equations, the first being twice the second:
