Answer:
The line is y = (1/2)x + 3
Step-by-step explanation:
We can calculate a slope. I'll use the two points (-4,1) and (-1,2.5).
Rise = (2.5-1) = 1.5
Run = (-1-(-4)) = 3
Rise/Run = Slope = (1.5/3.0) = 1/2
Find b, the y-intercept, by using point (-4,1) in the equation y = (1/2)x + b
y = (1/2)x + b
1 = (1/2)*(-4) + b
1 = -2 + b
b=3
The line is y = (1/2)x + 3
Answer:
first one is C
the second it is A
Step-by-step explanation:
the equation of a circle=(x-h)^2 + (y-k)^2 = r^2
h and k are the coordinate of the origin of a circle
to find the origin which is the midpoint of the diameter which has end points
(9,1) and (1,9)
h=9+1/2 = 10/2=5
k=9+1/2 = 10/2=5
(x-5)²+(x+5)²=r²
find r which is the half distance of the diameter
d of diameter : √(x2-x1)²+(y1-y2)²
d=√(9-1)²+(1-9)²
d=√8²+8²=8√2
radius=8√2/2=4√2
(x-5)²+(x+5)²=r²
(x-5)²+(x+5)²=(4√2)²
(x-5)²+(x+5)²=32
TR>TS the sides RS and TS are congruent opposite angles are equal.
9 deer is the area because if a square has 4 sides then you do 12 divided by 4 to get the length of each side. 3 times 3 is 9.
Answer:
19.7
Step-by-step explanation:
64 miles converts to 3.25 inches on the map
64/3.25 = 19.7 mi/inch
