two ways :
1. calculate the slope of the two lines, if it is same, they are parallel.
2. draw a perpendicular line ( 90 degrees) from on of the lines and if it intersects the other line at 90degrees then they are parallel

Do parallel lines need to look the same in a graph?
they need to look parallel
Will the graph of a system of parallel lines intersect at exactly 1 point?
Parallel lines don't intersect, no matter how many of them there are.
Lines drawn parallel to the axes of the graph?
Lines drawn parallel to the axes have only one letter.y=5 is horizontal, parallel to the x-axisx=5 is vertical , parallel to the y-axis.
Is there a way you can you tell if the corresponding lines are parallel?
If you can find the slope of both lines, then yes you can tell. The slope for parallel lines is the same - so if your slopes are the same, your lines are parallel. If you are measuring (less exact) the lines will be the same distance apart everywhere.
How many solutions will a system have if the graph of the solution is not parallel lines?
infinitely many solutions :)

What is it called when two lines on a graph do not intercept?
Parallel
Will the graph of a system of parallel lines intersect at exactly 1 point?
Parallel lines don't intersect, no matter how many of them there are.
Do graph of a system of parallel lines will have no solutions?
Correct. Unless the parallel lines are coincident, in which case the solution set is the whole line.
What are the deference between parallel lines and intersecting lines?
The difference between intersecting and parallel lines is that, on a graph parallel lines do ont touch,cross or anything. THEY NEVER TOUCH. intersecting lines touch, or cross eachother.\
How many solutions will a system have if the graph of the solution is parallel lines?
No Solutions
What do two variables with parallel lines on a line graph show?
correlation

Tell the difference between transversal lines and parallel lines?
The transversal is the line that cuts the parallel line.
A set of intersecting lines that appear at regular intervals?
Grid
How many solutions will a system have if the graph of the solution is not parallel lines?
infinitely many solutions :)
