Answer:
D
Step-by-step explanation:
You have to solve the compound inequality
The absolute value means the distance from the number b to the origin. Thus, the inequlity
has as solutions all numbers b that are at the distance from the origin greater than 6.
So,
Answer:
A. (1, -4)
Step-by-step explanation:
You can try the answers to see which works. (The first one does.)
Or, you can solve the equations algebraically. Equating y-values works well here:
2x -6 = -2x -2
4x = 4 . . . . . . . add 2x+6 to both sides; next divide by 4
x = 1 . . . . . . . . shows you selection A is correct

A graphing calculator can show you the point of intersection. Perhaps this is the way to go, since the unit seems to be on graphing systems of equations. Both of these equations are in slope-intercept form (y=mx+b), so are easily graphed by starting from the y-intercept (b) and using the slope (m=rise/run) to find another point on the line.
