50 years ago this material seemed difficult to me and now it seems clear and simple. Either you're a very good teacher or I'm 50 years smarter. Maybe a bit of both would be true.

The problem with the intercept method is it doesn't work if b=0. For example, y=5x. All you would get is the point (0,0) twice! In a case like that, I would revise my table and just work out the values of y when x=0 and when x=1. You'd then arrive at the fact that (0,0) and (1,5) lie on the line.

In my math class, our teacher always wanted us to have a set of 3 coordinates for linear equations. I think he did that to prepare us for parabolic equations.

Why come up with any theories? The only theory is simplicity. 1. If x and y are in the first degree, then the graph is a straight line. 2. Two points are needed to draw a straight line. 3. To simplify arithmetic calculations, we take alternately x and y equal to zero, because multiplying zero by any number will be zero. If the line passes through the point (0; 0), then we substitute any other number instead of x or y, for example 1. that's all. One minute of explanation is enough. For this example, at first it would be nice to simplify it by dividing the left and right sides of the equation by 2 and getting x + 2y = 6. More than 50 years ago, we did it like that.
Thanks. What's the practical use in our daily life? Thank you so much.

How long does it take you to get somewhere by plane, by train, by car? ...and so much more including every second of your daily life. How about vaccinated people VS unvaccinated and the number of deaths on both sides? Think of anything graphs apply.

@andtrrrot2 жыл бұрын
No. The assignment is to graph the line. The solutions are all the points on the line. If you plug 1,1 back into the equation, you can see that it is not a point on that line. 2(1)+4(1) does not =12. Substituting 1,1 back into the equation does not make a true statement. Therefore they are not a solution to the equation.

That is only 1 solution. A line is made up of an infinite number of points, therefore it has an infinite number of solutions. Besides, the assignment was to graph the line.
