The line of best fit for a scatter plot is shown:
1 answer:
In the slope intercept form, b represents the y intercept.
y = mx +- b
Therefore, if the y intercept is at 6, the formula of the line will look like
<span>y=mx + 6
</span>
This eliminates the first two options,
and
and leaves behind
and
Since the line you indicated is sloping downwards towards the lower right hand corner. It must have a negative slope.
Therefore, the answer must be the 3rd option.

You need to find "two-fifths of 30." Of here means multiplication:
There are 12 athletes in the club.
A system is linearly dependent, when multiplying one of the equations by a scalar, you get the other equation.
We then have the following system of equations:
Let's rewrite the system of equations.
To do this, let's multiply equation 1 by scalar -2:
We observe that we obtain equation 2 of the system.
Therefore, the system is linearly dependent.
Answer:
the following system is dependent:
x - y = 2 and -2x + 2y = -4
