Answer:
combined variation
Step-by-step explanation:
we have
we know that
a)<u> in the interval </u>----> (0,∞)
If the value of x increase the value of y increase
so
Is a direct variation
b) <u>in the interval -</u>---> (-∞,0)
If the value of x increase the value of y decrease
so
Is a inverse variation
therefore
Is a combined variation
Answer <u>(assuming it can be in point-slope form)</u>:
Step-by-step explanation:
With the given information, we can use the point-slope formula, , to write the equation of the line. Substitute values for the
,
, and
in the formula to do so.
The represents the slope, so substitute
in its place. The
and
represent the x and y values of one point the line intersects, so substitute -6 for
and -8 for
. This gives the following answer and equation (just make sure to convert the double negatives into positives:
