Answer:
Is an acute triangle
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to

we have
G(7,3), H(9, 0), I(5, -1)
step 1
Find the distance GH
substitute in the formula



step 2
Find the distance IH
substitute in the formula



step 3
Find the distance GI
substitute in the formula



step 4
Verify what type of triangle is the polygon
we know that
If applying the Pythagoras Theorem
----> is a right triangle
----> is an obtuse triangle
----> is an acute triangle
where
c is the greater side
we have



substitute


therefore

Is an acute triangle
For
ax+by=c
slope=-a/b
we have
-6x+1y=-4
slope=-6/-1=6
slope is 6
yint is where x=0
-6(0)+y=-4
0+y=-4
y=-4
yint is at y=-4 or (0,-4)
