geometry texts refer to an angle with a measure of 180° as a straight angle. In Figure 12 , ∠ BAC is a straight angle.
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
Answer:
y = -1/2x + 5/2
Step-by-step explanation:
Mid-point = ((-1 + 3) / 2 , (-5 + -1 )/ 2)
= (1 , -3)
Gradient = (-1 - -5 )/(-3 - -5)
= 2
m1_ = -1/2
y = mx + b ( we have to find b)
y = -1/2 x + b (we will use mid point x = x and y = y)
-3 = -1/2 (1) + b
-3 = -0.5 + b
b = -3 + 0.5
b = -5/2
so,
y = -1/2x + 5/2
The midpoint between m and r would be the difference between the two divided by 2 and then added to the lower number... For example the midpoint between 10 and 30 would be the difference between them (30 - 10 = 20) and divide it by 2 (20/2 = 10) and then add it to the number you started with (10 + 10 = 20). 20 is the midpoint.
So the midpoint between m and r would be..
(r - m) /2 + m
