Why cant all linear equations be written in point slope form?
Not all linear equations can be directly expressed in point-slope form because this form requires a specific point on the line and the slope. However, some linear equations, like vertical lines, do not have a defined slope (infinite slope), making it impossible to represent them in point-slope form. Therefore, while most non-vertical linear equations can be converted to point-slope form, vertical lines present an exception.
Linear equations in point slope form?
Point-slope form is written as: y-y1=m(x-x1), where (x1, y1) is a point on the line and m is the slope (hence the name, point-slope form).
Why do all linear equations that descrbe functions written in point slope form?
Linear equations in point-slope form describe functions because they express the relationship between two variables (usually x and y) in a way that defines a straight line. The point-slope form, given by (y - y_1 = m(x - x_1)), emphasizes a specific point ((x_1, y_1)) on the line and the slope (m), which determines the line's steepness and direction. This format allows for easy identification of a line's characteristics, making it a useful representation for linear functions.
If a system of linear of linear equations has infinitely many solutions what does this mean about the two lines?
If a system of linear equations has infinitely many solutions, it means that the two lines represented by the equations are coincident, meaning they lie on top of each other. This occurs when both equations represent the same line, indicating they have the same slope and y-intercept. As a result, any point on the line is a solution to the system.
Can linear equations have minus signs instead of plus signs?
Yes, and it would be a negative slope.

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.

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?

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 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

Yes, and it would be a negative slope.
What are the three forms of a linear equation?
1. Slope-intercept form (most commonly used in graphing) y=mx+b m=slope b=y-intercept 2. Standard form ax+by=c 3. Point slope form (most commonly used for finding linear equations) y-y1=m(x-x1) m=slope one point on the graph must be (x1,y1)
