If the lines intersect, then the intersection point is the solution of the system. If the lines coincide, then there are infinite number of the solutions for the system. If the lines are parallel, there is no solution for the system.

So people looking at the chart or graph will know what it depicts.
To answer this question, you would need to know at least one point on the graph.
If you are looking at a graph and you want to know if a function is continuous, ask yourself this simple question: Can I trace the graph without lifting my pencil? If the answer is yes, then the function is continuous. That is, there should be no "jumps", "holes", or "asymptotes".
Oh, dude, each individual point on a graph is called a "vertex." It's like the cool kid at the party who stands out from the crowd, you know? So yeah, next time you see a point on a graph, just give it a little nod and say, "Hey there, vertex, doing your thing."

by looking at it
They will be on the horizontal x axis of the graph (look for the x-intercepts).
If the arrows of the graph point down, then the vertex is a maximum because it is the greatest point on the graph. If the arrows point up, then the vertex is the minimum because it is the lowest point.
The mode has two or more bars on the graph with the same height.

A line on a graph with zero slope is a horizontalline.' Y ' is the same number at every point on the line.
An equation has an equal sign, which means that we know what the variable is equal to :)

The ordered pair (0, -6) Ordered pairs look like (x, y). they are the coordinates of a point on your graph. Asking if (0,6) is a solution to your equation means, does this point lie on the graph? Or algebraically, if you substitute in x = 0 and y = -6 into the equation, does it work? y = 5x-7 -6 = 5(0) -7 -6 = 0 - 7 -6 = -7 Well, -6 does NOT = -7, so we know that this ordered pair is not a solution to the function.
