So if the line is linear we can use slope intercept form to find the equation of the points: y=mx+b
To calculate m, the slope we subtract two of the points (I’ll use the first two):
(-1, 1)
(4, 0)
This equals 0-1/4+1, which simplifies to -1/5
So the slope is -1/5 and we can put that into slope intercept form along with a point to get b, the y-intercept.
So, y=-1/5x+b
Now we substitute x and y with a point.
1=-1/5(-1)+b
1=1/5+b
b=4/5
So the equation is:
y=-1/5x+4/5
I hope this helps!
H=henry's age
j=julia's age
r=rhianna's age
h is 3 times of j
h=3j
r is 1/2 times of j
r=(1/2)j or
2r=j
so
h=3j
2r=j
sub 2r for j
h=3(2r)
h=6r
henry's age is 6 times of rhianna's age
Answer:
The answer is C.....im pretty sure I took the test
Step-by-step explanation:
A secant is simply a line that intersects the circle at exactly two points.
Therefore, line GH is a secant of circle
B since it intersects the circle ast 2 points.
Area=length times width
area=28
length=7
28=7 times width
divide both sides by 7
4=width
the width is 4 miles
and perimiter is 22mi
