Answer:
(-5,-2)
(-4,-3)
(-6,-1)
Step-by-step explanation:
-5(x)-2(y)=-7
-4(x)-3(y)=-7
-6(x)-1(y)=-7
Alrighty
remember
means
and
and
for all real values of x
so
means
means
which simplifies to
1=x²+4x-5
minus 1 both sides
0=x²+4x-6
use quadratic formula or complete the square
and
2 solutions
A=(7,3) b=(7,-2) c=(1,-2)
Depends if it is a right triangle or not and if it is u will use the pothygerem theorem or the distance formula
