Mid point b/w pair of coordinate (xo ,yo) ,(x1,y1)
X = xo+x1/2
y= yo+y1/2
thus mid point between (-8,-8),(4,8)
X = -8+4/2= -2
y= -8+8/2 = 0
(-2,0) will be the midpoint
The graph of y = 3x + 1 has a slope of 3, for it to be steeper the graph should have a slope of more than 3.
Therefore, the equation to use is y = 7x + 1
(-11.2)+10.1 = -1.1
(-11.2) +10.1 and 11.2+ (-10.1) are related because the negative signs are switch so both equations have the same answer.
12 girls - 48%
48% ÷ 12 = 0.25
100% - 48% = 52%
1% - 0.25
52 % = 0.25 × 52 = 13 boys
120° is the correct answer<span />
