I'm not sure what you mean by "the" linear equation.
"A" linear equation is the equation of a line.
4x+7 = 2x + 5 is a linear equation in 1 variable.
If you were to solve for x, you would get x = -1 which, if graphed, is a vertical line.
For example y = 3x + 7 is a linear equation in two variables. This particular line has a slope of 3 and a y-intercept at (0,7). If graphed, it would pass through the y-axis at (0,7) and "rise" vertically +3 units for each horizontal "run" of +1 unit.
What else can I help you with?
What is the difference between linear and non linear graphs?
Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses.
Do linear graphs represent proportional relationships?
Do all linear graphs have proportional relationship
What graphs are used in finding trends in data?
Scatter graphs are best. Line graphs are OK if the trend is linear but not much good if the trend is non-linear.
What is the difference between a linear graph and a non linear graph?
Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses
What are two kinds of table graphs?
Linear and Exponetional.
What are linear graphs used for?
they are used for working algebra things
Do linear graphs always pass through origin?
No, they don't.
How can you use coordinate graphs to solve linear equations and linear inequalities?
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
Does in linear graphs the slope of the line change with the x-coordinate?
No. A linear graph has the same slope anywhere.
What do all direct variation graphs have in common?
All direct variation graphs are linear and they all go through the origin.
If two linear equations are in standard form how can you tell that the graphs are parellel?
If the slopes are the same on both graphs, they are parallel, and will never touch.
Difference between the graphs of linear equations and a direct variation?
Linear has a slope direct does not but both go through the orgin
