The answer to your question is A but i dont see a D option so it might be wrong
(1,4), (-1,3) 3-4/-1-1=-1/-2. -1/-2= 1/2 so 1/2 would be the slope
According to the statement 160 books were given to the class.
The correct option is C.
<h3>What is linear equation?</h3>
One or two variables make up a linear equation. Neither the numerator nor the denominator of a fraction can be a variable in a linear equation raised to a power higher than 1. All of the points on a coordinate grid sit on the same line when you identify the values that together make a linear equation true and plot those values.
<h3>According to the given information:</h3>
Let the no. of students be s:
Let the no. of books be b:
Given that there will be 20 books left after each student selects 4 books,
b = 4s + 20
And the remaining students take 5 books each, therefore b=5(s3), even if 3 pupils choose not to take a book.
comparing the value b
4s+20=5(s−3)
4s+20=5s−15
s=20+15
s=35
To do this, change the value of s in b=4s+20 to what is shown below:
b=4(35)+20
b=140+20
b=160
160 books were given to the class.
