Given:
Find-: Slope of the line.
Sol:
The slope of line is:

Where,

Choose any point:

So, the slope of the line is:

Slope of line is 3.
8·4=(x·7)-(x·3)
32=7x-3x
32=4x
x=8
This is your answer.
The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The standard form of a linear equation is given as:
y = mx + b
Where m is the rate of change and b is the y intercept (initial value of y)
Let y represent the amount of water Jaquan uses to wash x cars, Using the point (2, 24) and (5, 60):
y - 24 = [(60 - 24)/(5- 2)](x - 2)
y = 12x
For 6 cars:
y = 12(6) = 72
The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.

Answer:
y = - 4
Step-by-step explanation:
x = - 2
3x - 2y = 2
substitute x = - 2 into 3x - 2y = 2
3(- 2) - 2y = 2 ← step 1
- 6 - 2y = 2 ( add 6 to both sides ) ← step 2
- 2y = 8 ( divide both sides by - 2 )
y = - 4
