How do you find the equation of a line without graphing?
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 can you find the coordinates of two lines mathematically given the equation of both?
Subtract the equation of one line from the equation of the other
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
What does the equation allows you to find on any point on the line?
The x and y coordinates
Describe how to find the side length of the rectangle without graphing?
To find the length of a side, you either measure it, or you calculate it. How you calculate it depends on what data is given. For example, if you have the coordinates of the endpoints of a line, you can calculate the length by using the Pythagorean theorem (or simply subtracting the coordinates of the two endpoints, if the line is perfectly vertical or perfectly horizontal).
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.

guess it

How do you use a graphing calculator to solve quadratic equations?
Graph the equation then find the x intercepts.
How can you find the coordinates of two lines mathematically given the equation of both?
Subtract the equation of one line from the equation of the other
How do you find the equation of a line with two coordinates?
Assume the equation is y = kx + c Put in the x and y values of your known coordinates and sove the simultaneous equations.
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
An equation allows you to find the x- and coordinates of any point on the xy - plane?
Yes if it is a straight line equation
What does the equation allows you to find on any point on the line?
The x and y coordinates

How do you find the coordinates of y-intercept and x-intercept on a graph?
You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
