There are a couple ways to determine the equation of a line without graphing. How to proceed depends on what you know about the line.
Do you know a point, (x1, y1), and slope, m? Then use the point-slope formula,
Do you know two points on the line, say (x1, y1) and (x2, y2)? Then use the two-point formula,

How do you find coordinates of a line from an equation without graphing?
By substitution
How do you find the slope of a line segment without graphing it?
If you have an equation that looks like y=mx+b then the m is the slope. If you have two points then you use the formula Y2-Y1/X2-X1
When graphing inequalities which inequality line is solid?
The line that includes whatever variables are included in the equation.
How is graphing a linear inequality the same as graphing a liner equation?
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
How is graphing a linear inequality different than graphing a linear equation?
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
