It just wants you to simplify your expression. Does every single variable have a number in common?
Vertical line (when y = 0)
⇒ Equation : x = -1
Horizontal line (when x = 0)
⇒ Equation : y = -8
--------------------------------------------------------------
Answer: x = -1, y = -8
--------------------------------------------------------------
The first step is to divide by four to both sides
Answer:
The length of line segment AB is 9 units.
Step-by-step explanation:
To find this, you count how many squares there are between the two points. Hope I helped.
At the end of the directions, it talks about parallel, perpendicular, or neither. When x=y, the lines are perpendicular and have infinite solutions. When they are parallel, there is no solution. You'll get an answer like 4=5. Neither means there is only one answer, and you will get one x and one y.
