To find the slope of an equation given in ymxb balance the equation until y is by itself without any constants. In order to show you how to find slope of a table you have to know what slope is equal to. This video tutorial provides a basic introduction into the linear regression of a data set within excel.
You have all the information you need to draw a single line on the map.
The other method you can use is to plot the y-intercept. Now we can write a general formula for slope. For example if the equation is y 52x 7 the slope is 52. 6x - 2y 10 -2y 10 - 6x y 3x - 5 The slope of this line is 3 so the perpendicular slope will be -13.
