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
How do you find coordinates of a line from an equation without graphing?

How can you tell from a linear equation which direction it goes without graphing the equation?
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.
How do you find the slope of a line without graphing?
guess it

When graphing inequalities which inequality line is solid?
The line that includes whatever variables are included in the equation.
Can you tell the gradient without graphing the line?
If you have the equation, yes. If the equation is given in terms of x and y, make y the subject of the equation. That is, expres the equation in the form y = mx + c where m and c are constants. Then the gradient is m.

How do you figure out the equation of a table with a graphic calculator?
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.

Solve the system of liner equation by graphing 2x plus y1and y2x plus 1?
Without any equality signs the given expression can't be considered to be straight line equations.
Find the slope of the line whose equation is 4x - 6y 8?
Without an equality sign the given terms can't be considered to be a straight line equation.
Find the slope of the line whose equation is 17 plus 3y 7x.?
Without an equality sign the given terms can't be considered to be a straight line equation.
