Answer:
a) slope / m = 3
b) y-intercept / b = 0
c) Proportional
Step-by-step explanation:
a)
( y1 - y2 ) / ( x1 - x2 )
( 6 - 12 ) / ( 2 - 4 )
( -6 ) / ( -2 )
6 / 2
3
b)
y = mx + b
6 = 3(2) + b
6 = 6 + b
0 = b
c)
Proportional is when it crosses origin ( 0, 0 ).
Not proportional is when it does not cross origin.

Answer:
<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of books in the children's section at the local library = 500
Ratio 2:3 for picture books and chapter books
2. How many chapter books are in the section?
We will use the Rule of Three Simple for answering this question, this way:
Chapter books Total books
3 5
x 500
x * 5 = 500 * 3
5x = 1,500
x = 1,500/5
x = 300
<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>
Option(d)is the answer...
We know that area of the triangle is 1/2bh
=>1/2*7.2*4.8
=>3.6*4.8
=>17.28in sq....
=>17.3in sq(approx)....
Hope this helps u.....
The piecewise function graphed on the axes is defined as follows:
<h3>What is a piecewise function?</h3>
A piecewise function is a function that has different definitions, depending on the input.
For x up to 1, we have that there is a <u>linear function with an intercept of 5 and a slope of -2</u>, hence the definition is:
f(x) = -2x + 5, x ≤ 1.
For x greater than 4, we have a <u>linear function with a slope of 2,</u> hence:
f(x) = 2x + b.
When x = 5, f(x) = 6, hence the value of b is found as follows:
6 = 2(5) + b
10 + b = 6.
b = -4.
Hence the second definition is:
f(x) = 2x - 4, x > 4.
