Answer:
13
Step-by-step explanation:
a = 5
b = -8
5 - -8 = 13
Step-by-step explanation:
I think the answer is like this
To determine the location of a point on a graph, the first number of the ordered pair is a x-coordinate which means the first number you would look for would be the horizontal line, or the x-axis. The second number is the y-coordinate which means that you would look on the vertical line, or the y-axis. You would go on the horizontal line first, then from there go up to the y-coordinate and place your point. (I'm sorry if it's long but you can try to shorten it.)
Hope this helped!
Have a nice day!
12/2 = 6, so;
7x-1 = 6
7x = 7
x = 1
Because both sides are equal, you do the same for 2x+4
2x+4 = 6
2x = 2
x = 1
B) If the line is parallel, that means the slope is the same.
The slope for the original line is

=

.
The second form of coral line would be y = -1/4x + (any number). You could use
y = -1/4x + 3.c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So
yes, the third coral structure is perpendicular to the first coral.
