2. y=2x+3
When x =0 and y= something, the 'something' is your y-intercept which is b in the y=mx+b formula. Then we look at what is changed in the x and y value to determine the m part. the x increase by 1 and y increase by 2 so the m part is 2.
3. y=-7x
Same as the last one, there is no y-inter this time because the y=0 when x=0/ So the y deceased by 7 each time and x incease by 1 so it is -7 for the m part.

Answer: Do you mean a pie chart or a dessert pie? anyway i will answer for the pie chart
Step-by-step explanation:
pie charts are used in data handling and they are circular divided up into different segments which each represent a value or a different size
24* 80/100 = 24*8/10 = 19.2 is the answer.
The value of sin(2x) is 
Explanation:
Given that 
The formula for 
is 
Since, 
Also, it is given that
Thus, 
and 
To find the hypotenuse, let us use the pythagoras theorem,
Now, we can find the value of sin x and cos x.
Now, substituting these values in the formula for sin 2x, we get,
Thus, the value of sin(2x) is
