Without an equality sign the given expression can't be considered to be an equation.
If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)
I would not say it is "needed," but basically the more points you have the better you can understand the graph. And three because its the recommmended minimum to get a gist of the graph, yet it will not take a lot of effort to plug in three numbers.
If you mean to say (x^2)-2x+4=0 then there is no solution for x because the equation never makes it to 0 If you mean to say 2x-2x+4=0 then there is no solution for x because it is a horizontal line at Y=4
undefined means you can not do the operation (5/0 is undefined) no solution refers to an equation not having an answer. a solution is a number which you can plug into the variable of an equation and get a true statement. So having no solution means there is no number which you can plug in and get a true statement. As a fraction is not an equation, but an expression it is not right to say that 5/0 has no solution. There is no variable in 5/0, nothing to plug into to get a true or false statement.

Let's say you have the quadratic equation x2 - 7x + 12 = 0. Plot the graph of y = x2 - 7x + 12. Where y = 0 (when the graph crosses the x-axis) is a solution to the equation. In this case, it crosses at the points (3,0) & (4,0) so the solutions are x = 3 and x = 4. Now if the graph never touches the x-axis, that means the solutions to the equation are complex numbers.
The graph of an equation has a slope and intercept.[ 13x - 11y - 12 ] is not an equation, and has no graph,until you say that it's equal to something.
Nothing yet. It only means that the equations you have are not independent ...one of them is a simple multiple of another one. All you can say so far is thatyou need another equation.
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."
Generally, when we say a quadratic equation has no solutions, it means that the graph does not cross the x-axis at all.In other words, it means that there are no values for x when y equals 0 (because the line y=0 IS the x-axis.)Hope that helps.Jamz159
An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.

-- I can say that the equation of the line is [ x = a number ]. -- I can also say that the line is vertical on a graph. -- I can also say that the line is parallel to the y-axis. -- Also that it's perpendicular to the x-axis.
