The midsegment is half the length of the base. So the base = 2*4 = 8 in.
Since it is an isosceles triangle, the other two sides are equal in length.
Perimeter = sum of two equal sides + base = 20 in.
2x equal side + 8 = 20
equal side = 12/2 = 6
Each of the equal sides = 6"
Y-6=-14/11(x+4)
The slope is (6+8)/(-4-7), by the equation y1-y2/x1-x2. This equals -14/11.
In point slope, you follow the form y-y1=m(x-x1) where m is the slope, and x1 and y1 are two points on the coordinate plane. If you substitute in (-4,6), you get the second answer choice, y-6=-14/11(x+4)
