The ordered pair (6 , 4) is a solution for y - 4 = 7(x - 6)
Step-by-step explanation:
The point-slope form of a linear equation is:
, where
- m is the slope of the line
is a point on the line
Any point on the line is a solution for the equation of the line
The solution of an equation is the values of x and y which make the left hand side is equal to the right hand side
∵ The equation is y - 4 = 7(x - 6)
- Compare the equation by the point-slope form above
∴ m = 7
∴
= 6 and
= 4
- That means point (6 , 6) lies on the line
∴ Point (6 , 4) is a point on the line which represents the
given equation
∵ Any point on a line is a solution of the equation of that line
∴ (6 , 4) is a solution of the equation
The ordered pair (6 , 4) is a solution for y - 4 = 7(x - 6)

Step-by-step explanation: is this the answer?
Answer:
4th one is correct
Step-by-step explanation:
There are no expressions to choose from, but it should look something like:
y= total cost= $74.50
x= number ordered= 10
c= cost per lunch= 74.50/10= $7.45
The more lunches that are ordered, the higher the total will go. y depends on what x is.
y= $7.45x
OR
$74.50= 10c
CHECK:
$74.50= $7.45 per lunch * 10 lunches
$74.50= $74.50
ANSWER: y= $7.45x OR $74.50= 10c
Hope this helps! :)
