Standard deviation is the average distance between two points on the graph. If the standard deviation (sd) is high, then the variables relationship is more spread out and unlike one another. The smaller the sd, the closer and less varied the variables are.

What is the slope of the line whose equation is -48 = 2x - 8y?<br> Enter your answer in the box.
aleksandr82 [10.1K]

Answer:

The slope is \frac{2}{8}

Step-by-step explanation:

Take the general equation of a straight line y = mx+c

Here m is the slope of the line.

So let's get the equation of the line in the question in the same form.

-48 = 2x-8y

Add 8y to both sides: 8y - 48 = 2x

Add 48 to both sides: 8y = 2x + 48

Divide by 8 to get it into the general equation: y = \frac{2}{8} x + 6

Now compare it to the general equation to find the value of m. The value of m is the coefficient of x which we can see is \frac{2}{8}
