Answer:
y = -3/7x + 5
Step-by-step explanation:
y2 - y1 / x2 - x1
2 - 8 / 7 - (-7)
-6/14
= -3/7
y = -3/7x + b
2 = -3/7(7) + b
2 = -3 + b
5 = b
The solution to the given equation is w = -5
<h3>Solving of expression</h3>
What is an Algebraic Expression? An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations
Given the expression below as shown;
-10w = 50
Divide both sides by -10
-10w/-10 = 50/-10
w = -5
Hence the solution to the given equation is w = -5

The answer is 86. Hope this helps.
Answer: 115, 2645
(x= 115, y= 2645)
Step-by-step explanation:
There are two methods to this, which is using the graph with each x and y value, or substituting in values.
I would suggest looking at the graph first and then substituting values so you know the equation is being satisfied by the ordered pair.
In this case, one way to check it could look like this (substituting y value):
y = 23x
2645 = 23x
x = 2645÷23
x = 115
C = 2 * 3.14 * 4 = 25.1 to nearest tenth ( 1 decimal place)
