9×29 equals 225 = two hundred twety-five
1192.64-819.73 is 372.91
so... if we take 1192.64 to be the 100%, how much is 372.91 in percentage then?
The y-intercept is the "b" in the slope-intercept form of y=mx+b. Based on the equation you wrote, you can substitute each of your known values into the slope-intercept form.
If length AM = AK then it is isosceles.
M(-1,-6), A(-4,5)
AM=((5-(-6))²+(-4-(-1)))^(1/2)=11.401
A(-4,5) and K(5,-2)
AK=((-2-5)²+(5+4)²)^(1/2)=11.401
so the triangle is isosceles.
