Step-by-step explanation:
The line
Is in point Slope form. This means the Slope and the y intercept are visible in the equation 9f the form
Where m is the Slope of the line and b is the y coordinate of the y intercept.
To determine the y intercept, assume x = 0, then - 3x = 0, so y = 3 and x = 0 (0,3}
From that point you can find the next point by choosing a value for x in the given equation to find a corresponding y.
Substitute 1 for x and get 0 for y, (1,0)
Substitue 2 for x and get - 3 for y, (2,-3)
To answer the questions use the supplied coordinates in the original equation.
#1. (-1,6)
This is a true statement, so the line does pass through this point.
#2 (12,-33)
Again, the statement is true, so the line passes through the point.
#3 (2,9)
This is a false {untrue} statement, so the point does not sit on the line.
Answer: A
Step-by-step explanation: -20
To answer the question above, factor each number and determine the biggest common factor.
42 = 6 x 7
63 = 9 x 7
105 = 15 x 7
The common factor for these numbers is 7. Thus, the fabric pieces should be 7 inches long.

Step-by-step explanation:
The area of the rectangle can be written as:
here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.
The perimeter of a rectangle can be written as:
To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.
now we can substitute this 'h' into our equation of the perimeter.
and voila! we have expressed P in terms of x only.
this can be written as P as a function of x as:
