You can follow the following steps.
* First, you determine the slope between the two points. Just calculate delta-y / delta-x (that is, difference in y-coordinates, divided by the difference in x-coordinates, between the two points).
* Next, you use the point-slope formula, to get an equation for the line. You can use any of the two points for this; each of the points will give you an equation that looks different, but the two equations are equivalent, if you do everything correctly.
* Finally, solve the resulting equation for "y"; that will give you the equation in slope-intercept form.

What is the equation of a line that passes through the points 4 8 and 1 2?
You haven't given points, you've just given single values. for there to be a point in a plane, you need 2 coordinates, both x and y
What is the prediction method used to estimate a point on a line that does not lie between the given points?
The answer is linear extrapolation.
What points are on the line given by the equation y equals x?
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
What is the given points for the equation y equals 2x-3?
5
What points are on the line given by the equation y -3x 5?
But it's not an equation because there is no equal sign and no points are given.
