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.
\n" ); document.write( ";
\n" ); document.write( "This involves finding the slope(designated as \"m\")from two pairs of the x,y values
\n" ); document.write( "Take these two pair and assign them as x1, y1 and x2, y2
\n" ); document.write( ":
\n" ); document.write( "Find the slope using the following formula: m = $\"%28y2+-+y1%29%2F%28x2+-+x1%29\"$
\n" ); document.write( ":
\n" ); document.write( "Once you have the value for m, write the equation from the following
\n" ); document.write( "formula: y - y1 = m(x - x1), note that you do not use x2 and y2 here.
\n" ); document.write( ":
\n" ); document.write( "Substitute the same values for x1 and y1 and m, then simpilfy until you
\n" ); document.write( "have y = mx - b form of the equation, this describes the relationship between x and y.
\n" ); document.write( ":
\n" ); document.write( "If this does not help you, submit an actual table along with the specific question and someone will take you through it. \n" ); document.write( "
