It shows the Y Intercept, meaning when it would cross the Y axis, and it also shows the slope of the line, and whether it is downward sloping or upwards.
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
They are alike in that you graph the lines in the same way, but they are different because you have to shade in one side of the line
The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.
When graphing a linear inequality, the first step is to replace the inequality symbol with an equal sign to graph the corresponding linear equation. This creates a boundary line, which can be solid (for ≤ or ≥) or dashed (for < or >) depending on whether the points on the line are included in the solution set. After graphing the line, you then determine which side of the line represents the solution set by testing a point (usually the origin if it's not on the line) to see if it satisfies the original inequality. Finally, shade the appropriate region to indicate the solutions to the inequality.
By substitution

You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
It depends on which calculator! If the data is linear, you can estimate the slope of the line and the y-intercept from graphing the data. By graphing the data, you will be able to tell if it forms a straight line or not.
The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.
A linear equation describes a line like 2x+1=y. If you were to graph that equation, then it would give you a line. A quadratic equation is like x^2+2x+1=y. Graphing this equation would give you a U shaped graph called a parabola.
a linear graph is a graph where the line is ongoing and doesn't change directions
If it is <= or >=
By substitution
When it is a linear equation.
It is a linear equation.
Y = 5X - 3It form a linear function; a line.
