So point slope form is y=mx+b where m=slope and b=y intercept so
in (x,y) form
one solution is x=1 and y=3, also slope is 2 so
m=2
subsitute
3=2(1)+b
3=2+b
subtract 2
1=b
equation is
y=2x+1
tricky answers so simplify them
A: y-1=2(x-3)
distribute
y-1=2x-6
add 1
y=2x-5
not the answer
B: y-3=2(x-1)
distribute
y-3=2x-2
add 3
y=2x+1
correct
the answer is B
There are 18 cookies divided by 3 friends so each friend gets 6 cookies.
We know that the ride that Rohan wants to take lasts for 3 minutes, and goes up to maximum speed of 75 miles per hour
We have to find the domain and range
Domain: all possible values of the independent variable
Range: all possible values of the dependent variable
In this situation, the independent variable is time and the dependent variable is speed
Hence,
Domain = [0,3] minutes
Range = [0,75] miles per hour
Answer:
I not for sure but I'm pretty sure B.
