1 answer:
The linear equation of the points is y = 2x + 3
<h3>How to determine the equation?</h3>The points are given as:
(-2, -1), (-1, 1), (0,3), (1,5), (2,7), (3,9)
From the above points, we can see that:
As x increases by 1, the y value increases by 2
This means that the points form a linear equation, and the slope (m) is calculated using:
m = Δy/Δx
This gives
m = 2/1
m = 1
The y-intercept (c) is when x = 0.
From the points, we have:
(x,y) = (0,3)
This means that
c = 3
A linear equation is represented as;
y = mx + c
Substitute the known values
y = 2x + 3
Hence, the linear equation of the points is y = 2x + 3

Answer:
<u><em>C, </em></u> Expression B and Expression D
Step-by-step explanation:
<h2><u><em>Step 1 : Analyzing the question:</em></u></h2>The regular price of an item at a store is p dollars. The items is
on sale for 10% off the regular price. Some of the expressions
below represent the sale price, in dollars, of the item.
It says " <em>item on sale for 10% off </em>". That means or
.
Expression A: 0.1p
Expression B: 0.9p
Expression C: 1 - 0.1p
Expression D: p - 0.1p
Expression E: p - 0.0p
<u>Expression A</u> doesn't make any sense. It only shows the how
much you save
<h3><em><u>Expression B:</u></em> This is one of the answer. </h3><h3 /><h3><u>Expression C: </u> You can't subtract from
<u>Expression E: </u> This is the same thing as
<u><em>The answer is C .</em></u>
