y= 2x -6
Examples of equations in standard form?
To be able to write the equation of a line in standard form. In particular, our book would not have cleared the fraction.
Finding equations of lines as solutions?
find equation of the line. write equation in slope intercept form. (5,5) parallel line (3,13) and (12,13)
Which of the following is the standard form of the equation of a horizontal line?
y = b
which of the following is standard form of the equation of a horizontal line?
y=b
Which of the following equations of a line is in standard form?
2x + 3y = 6
Which of the following equations of a line is in slope-intercept form?
y= 2x -6
What is function as equations in two variables?
Straight line equations have two variables in the form of x and y
How do you find the slope of the line if the equations in standard form?
There is more than one "standard form". If the equation is not already solved for "y", solve it for "y". In that case, you'll get an equation of the following form (known as "slope-intercept form"): y = mx + b Where "m" is the slope of the line, and "b" is the y-intercept (the point where the line intercepts the y-axis).
Do linear equations form a line?
Yes, the graph of a linear equation can be a line. There are special cases, sometimes trivial ones like y=y or x=x which are linear equations, but the graph is the entire xy plane. The point being, linear equations most often from a line, but there are cases where they do not.

Equation of line?
There are several equations; sometimes one can be more appropriate, sometimes another, depending on what data is given. For example, an equation solved for "y", i.e. of the form y = mx + b directly shows you the line's slope (which is "m") and the y-intercept (which is "b"). On the other hand, a general form of an equation of a line is ax + by = c This form is able to represent vertical lines, which can't be expressed with the slope-intercept form. There are several other equations for a line as well.
Finding equations of lines as solutions?
find equation of the line. write equation in slope intercept form. (5,5) parallel line (3,13) and (12,13)
When writing linear equations how do you determine which form of a line to use?
It does not matter because they are equivalent. You can always convert from a slope-intercept form to a standard linear form (and vice versa).
Who introduced system of equations with coordinate axes?
It was the Frenchman Rene Descartes who intoduced straight line equations in the form of y = mx+c whereas m is the slope and c is the y intercept
Is it possible to have two different looking equations in the same version of point slope form for the same line?
It depends on what constitutes different looking: how similar must the equations be before you see that they are the same. If both equations are in the point-slope form, the coefficients of one equation must be a fixed multiple of the coefficients of the other.
Which of the following is the standard form of the equation of a horizontal line?
y = b
