Segment A is a linear constant. In general a linear constant will be y=k for a horizontal line or x=k for a vertical line.
The equation of the line is 
Explanation:
The equation of the line is perpendicular to
The equation is of the form
where m=-14
<u>Slope:</u>
The slope of the perpendicular line can be determined using the formula,



Thus, the slope of the line is 
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,

Substituting the slope
and the point (2,-4), we get,

Simplifying, we get,



Thus, the equation of the line is 
Step 2 because he/she took out the parentheses when he/she wasn’t supposed to!
Answer:
a)13x+3
b) -3x-13
c)4x^2-24
d)-3x^2 +3x
Step-by-step explanation:
a) combine like terms
5x-3+8x+6 so combine the -3 and +6 and 5x and 8x
So 13x+3
b)There is an invisible one in front of (2x-5) and an invisible -1 in front of (5x+8). Distribute these.
2x -5 - 5x -8
So -3x-13
c) Distribute the four to everything in the brackets.
4(x^2-6) becomes 4x^2-24
d) Distribute:
-3x (x-1) becomes -3x^2 +3x
