graph of y=ax+b in excel
Excel doesn't take inputs in the form of a line which is y=ax + b. It simply
requires a list of the x points and y points. Excel automatically calculates the a value and the b value. you enter points in two rows or two columns Col A Col B (x values) (Y values) 1 4 2 7 The a value is the slope = (delta y)/(delta x) = (7 -4)/(2 -1) = 3 Y = ax + b 7 = (2*3) + b b = 1 Excel does the calculation above automatically.
