Question 98533: I am a mother trying to help her child solve equations, and find linear relations and linear function when given four tables with X and Y columns, each table having a different set of numbers. It asks to write an equation, describe the linear relation and the function. Please help...Thanks

You can put this solution on YOUR website! I am a mother trying to help her child solve equations, and find linear relations and linear function when given four tables with X and Y columns, each table having a different set of numbers. It asks to write an equation, describe the linear relation and the function.
;
This involves finding the slope(designated as "m")from two pairs of the x,y values
Take these two pair and assign them as x1, y1 and x2, y2
:
Find the slope using the following formula: m = 
:
Once you have the value for m, write the equation from the following
formula: y - y1 = m(x - x1), note that you do not use x2 and y2 here.
:
Substitute the same values for x1 and y1 and m, then simpilfy until you
have y = mx - b form of the equation, this describes the relationship between x and y.
:
If this does not help you, submit an actual table along with the specific question and someone will take you through it.
