Answer:
a) (-1,4.5)
b)10.63 units
c)7/8
Step-by-step explanation:
a) To find this, we use the midpoint formula
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (3,8)
(x2,y2) = (-5,1)
(x,y) = (3 -5)/2 , (8 + 1)/2 = (-1, 4.5)
b) To calculate the distance D between two points, we use the formula;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(-5-3)^2 + (1-8)^2
D = √(-8)^2 + (-7)^2
D = √64 + 49
D = √113
D = 10.63 units
C) We use the slope formula here
m = (y2-y1)/(x2-x1)
m = (1-8)/(-5-3) = -7/-8 = 7/8
Answer:
The slope is 1/2
Step-by-step explanation:
The equation is y= 1/2x +2
So the slope would be 1/2
6.50-2.25=x

Answer:
f(-6) = -21
Step-by-step explanation:
Substitute x = -6 into f(x):
f(-6) = 3(-6) + (-6 ÷ 2)
= -18 - 3
= -21
