Answer:
and x=4
Step-by-step explanation:
We are given that a curve
We have to find the equation of tangent at point (4,2) on the given curve.
Let y=f(x)
Differentiate w.r.t x
By using the formula 
Substitute x=4
Slope of tangent
In given question
By comparing we get a=4
Point-slope form
Using the formula
The equation of tangent at point (4,2)
You have to consider the sample space. In this example the sample space
is {1,2,3,4,5,6}
A simple event can be defined as a SINGLE outcome : Example getting a 3 OR 5 OR any other number from the sample space.
Now if you roll 1 dice & you want to get an even number (2,4,6) then you have chosen from the sample space 3 outcome & this is a compound event
Equally if you roll 2 dice and want to get "one" and/or "three" this is a compound event since you have chosen 2 outcome from the sample space.
Mind you, if you want 5 And 5 when rolling two dice it's a simple event because you have chosen ONE outcome from the sample space.
Hope this will help you to understand this kind of problem
1. A=(0,4)
2. B=(4,1)
3. Slope=-3/4
If you type in both the coordinates it’ll give you the answer on google. That’s how I did this.
