Answer:
y=3x+3
Step-by-step explanation:
y=mx+b is slope intercept form
to find the slope(m) you need to plug your numbers into the equation y(2)-y(1)/x(2)-x(1)
which means subtract the Y's together and the X's together and put the quotient of the Y's on top. Note that you have to choose a set of number to be the first group and the other set as the second group
so (0-6)/(-1-1) = -6/-2 = 3
3 will be your slope. plug that and a set of your numbers into the slope intercept equation
0=3(-1)+b
0=-3+b
3=b
y=3x+3
Each centimeter on the map represents 20 miles in real life. Similarly, every twenty miles in real life would be represented as 1 centimeter on the map.
Answer:
it would take 10 hours
Step-by-step explanation:
Answer:
or 
Step-by-step explanation:
Given:
We are to find the values of 
such that these two functions are equal.
Substitute 
.
We get 
Hence for we have the functions to be equal.
Now for 
We see the functions are once again equal.
