<h3>What is the general equation of a straight line?</h3>The general equation of a straight line is -
y = mx + c
where -
m is the slope of line
c is the y - intercept
Given is the equation of a straight line.
The given equation is -
y = 5 - 1/2x
We will find the values of [y] for given subsequent values of [x] given.
y(-2) = 5 + 1 = 6
y(0) = 5 - 0 = 5
y(2) = 5 - 1 = 4
y(4) = 5 - 2 = 3
The coordinates are plotted on the graph attached with answer.
Therefore, the complete table and the plotted graph is as follows -
x y
-2 6
0 5
2 4
4 3

Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of
Step-by-step explanation:
A temperature falls from 0 to in
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is
Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:
x° = - 3.5
x° =
Thus per hour; the temperature falls at the rate of
