Regina graphs the relationship between temperature (in °C) and elevation (in m) in 9 different cities (shown below)
What is the meaning of point A?

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

one set of data has more variation than the other. hope this !

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
