Answer:
Area of triangle= 1/2 x base x height
Area of triangle




Therefore the area of the triangle is 45.5inch
Answer:
The change in delta x would be 0 in the second option because the change is exactly the same.
Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7
Answer:
Midpoint coordinates are 
Step-by-step explanation:
The Coordinates of R = (-8,3)
The Coordinates of S = (9, -7)
Let M be the mid point of M and its coordinates by (x,y)
Now, by mid point formula,

⇒
So, the midpoint coordinates are
