Explanation:

The line can be understood as an infinite set of points aligned in a single direction. A line can be expressed by an equation that follows the model y = m * x + b, where "x" e "y" are the variables in a plane. This model is called "slope-intercept form." In this expression m is called the slope of the line and is related to the inclination of the line, and b is the independent term and is the value of the point at which the line cuts to the vertical axis (y axis) in the plane. In general, the slope represents the variation of y with respect to the variation of x too.

In this case you have the equation: 3*x-4*y=12

So, first of all it is convenient to solve for "y".This means that "y" will be isolated to obtain the "slope-intercept form." For that in first place subtract 3 *x from both sides of the equation.

3*x-3*x-4*y=12-3*x

-4*y=12-3*x

Then divide each term by -4

$\frac{-4*y}{-4} =\frac{12}{-4} -\frac{3*x}{-4}$

$y =-3 +\frac{3}{4} *x$

Rewriting in pending-intersection form.

$y =\frac{3}{4} *x-3$

Then the slope is $\frac{3}{4}$ and the value of b (y-intercept) is -3.

So the y-intercept is (0,3).

Now substitute 0 for y to find the x-intercept:

$0=\frac{3}{4} *x-3$

$3=\frac{3}{4} *x-3+3$

$3=\frac{3}{4} *x$

$\frac{3}{\frac{3}{4} } =\frac{\frac{3}{4} }{\frac{3}{4} } *x$

$3* \frac{4}{3} =1*x$

$\frac{12}{3} =x$

4=x

So the x-intercept is (-4,0).

As any line can be plotted using two points, using the intersections in "x" and "y" the equation will be plotted as shown in the attached image.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
