The length of the midsegment is 22
Answer: 132
Step-by-step explanation: There are all equal distances making it the same degree on the interior
Slope = (10-1)/(1+2) = 9/3 = 3
y = mx + b
1 = 3(-2) +b
1 = -6 + b
b = 7
equation
y = 3x + 7
or
3x - y = -7
answer is <span>3x − y = −7 (first choice)</span>
No because y=5 is a horizontal line on a graph, in this scenario the x-values would stay the same
