1) y= -4x+c
2) y= 3x+c replace x and y to find c , 5=3(2)+c
C= -1
Y=3x-1
3) find slope first m=y2-y1/x2-x1 = 0-(-1)/-2-1 = 1/-3 and now you have y= -1/3x+c to find c just replace any of the given points , 0= -1/3(-2)+c
C= -2/3 and so y= -1/3x-2/3
4) DO THE SAME STEP AS NUMBER 3 and enjoy!
Answer:
2/5
Step-by-step explanation:
The slope is given by
m= (y2-y1)/(x2-x1)
= (4-2)/(3 - -2)
= 2/(3+2)
= 2 /5
Answer:
b.g(x)=
+3
Step-by-step explanation:
If two graphs have the same shape and you only want to change one's y intercept, you just have to add or subtract the number at which you want the graph to intercept the y axis from the equation
Answer:
80 minutes
Step-by-step explanation:
1 hour=60 minutes
2 hours=120 minutes
-------------------------------
15/120=10/x
cross product
120*10=15*x
1200=15x
x=1200/15
x=80
Length of the arc = radius x θ = 8 x 45 x π/180
= 8 x π/4 = 2π = 6.28 in ~ 6.3 in
