Lines equation

I explain the basic work of finding the line equation and make work on easy. You will find more problems to study and deferent kinds. This is first lecture I focused to learn you how to deal with equation line, finding the slope usually in first step and deal with equating solve more problems and I want give advice resolve this problems just change the numbers or look for similar problems to solve this way you will be perfect with this subject study of high school.

An important topic of high school algebra is "the equation of a line." This means an equation in x and y whose solution set is a line in the (x,y) plane.

The most popular form in algebra is the "slope-intercept" form :
y = mx + b.

This in effect uses x as a parameter and writes y as a function of x: y = f(x) = mx+b. When x = 0, y = b and the point (0,b) is the intersection of the line with the y-axis.

Thinking of a line as a geometrical object and not the graph of a function, it makes sense to treat x and y more evenhandedly. The general equation for a line (normal form) is : ax + by = c

Now we will solve a problems to show you how it is easily :
