<span>Min: 10 </span>
<span>Median: 17 </span>
<span>Max: 25 </span>
<span>lower Quartile: (10+15)/2 = 12.5 </span>

Answer:
Step-by-step explanation:
when dividing subtract the exponents
First find the slope of this new line; it's the same as the slope of the "given line," which you unfortunately have not yet given. Let's call that slope "m."
Then, the equation in point-slope form of the new line is
y - (-1) = m(x - [-1]), or y+1 = m(x+1)
Please go back to the original question, obtain the slope of the "given line," and substitute that value for m in y+1 = m(x+1).
