Answer:
The ordinate of B exceeds the ordinate of A by 7
Step-by-step explanation:
Let
A(x1,y1),B(x2,y2)
where
x1 is the abscissa of A
x2 is the abscissa of B
y1 is the ordinate of A
y2 is the ordinate of B
we know that


so
-----> equation A
----> equation B
substitute equation B in equation A
therefore
The ordinate of B exceeds the ordinate of A by 7
Answer:
What is a factor?
Step-by-step explanation:
Answer:
(a) 
(b) 
(c) Answer of part a is equation of line
which is parallel to y axis and in part by equation of line is
which is parallel to x axis
Step-by-step explanation:
We have given points are 
(a) Equation of line is given x = -9
We have to find the equation of line parallel to x= -9 and passing through 
x = -9 line is parallel to y axis and so slope will be infinite
Equation of line is given by 
So 

(b) Equation of line is given 
This line is parallel to x axis so slope will be zero
So equation of line will be 

(c) Answer of part a is equation of line
which is parallel to y axis and in part by equation of line is
which is parallel to x axis
I think the answer is substitution property of equality because you are substituting 9 for y as y=9.
Answer:
Examine the mathematical expression you're working on. For example, suppose you're given 5x + 3. There are two terms here, 5x and 3. Look for the variable. In this case, x is the variable. In your case its c
Find the numerical coefficient of x. Remember to look for the number before the variable. In this case, 5 is the numerical coefficient. The term 3 is a constant and is separated from the variable by a plus sign.
Keep an eye out for negative coefficients. For example, suppose you're given the statement -y + 7 + 98. You would first identify the variable, y.
Look for the numerical coefficient of y. In this case, a "1" is implied before the variable, but it's negative in this instance. Therefore, the coefficient of y is negative 1.
