Can linear equations have minus signs instead of plus signs?
Yes, and it would be a negative slope.
Why can't all linear equations be written using point slope?
Because of undefined slope, because undefined slope does not have a slope it doesn't have anything to substitute for m in the point slope equation.
How can you tell if two equations are parallel?
if they have the same slope If two linear equations are inconsistent - that is, have no solution, then the graphs would be parallel and have the same slope if their slope is defined. Example: x + y = 1 x + y = 2 Example with no slope: x = 1 x = 2
What is the basic equation for graphing linear equations?
y=mx+b m is slope. slope is rise over run b is y-int
What are the different ways of graphing linear equations in two variables?
slope intercept form, rise over run
By looking at two linear equations how can you tell that the corresponding lines are parallel?
By looking st two linear equations you can tell that the corresponding lines are parallel when the slope is the same. The slope controls where the line is.
How do you use slope to graph linear equations?

What is the importance of slope intercept form?
makes it very easy to graph linear equations
Difference between the graphs of linear equations and a direct variation?
Linear has a slope direct does not but both go through the orgin
Does every pair of linear simultaneous equations have a solution?
Actually not. Two linear equations have either one solution, no solution, or many solutions, all depends on the slope of the equations and their intercepts. If the two lines have different slopes, then there will be only one solution. If they have the same slope and the same intercept, then these two lines are dependent and there will be many solutions (infinite solutions). When the lines have the same slope but they have different intercept, then there will be no point of intersection and hence, they do not have a solution.

What is the definition of Simultaneous Linear Equations?
A system of linear equations is two or more simultaneous linear equations. In mathematics, a system of linear equations (or linear system) is a collection of linear equations involving the same set of variables.
Why can all linear equations that describe functions be written in point slope form?
Because a linear equation is, by definition, a straight line. Any line can be defined by selecting any one point on the line and the slope of the line.
