To draw a straight line graph using known points in GeoGebra is a little trickier. First you have to plot the points first. [br]This is done by typing in the points in the form of (x,y) in the input bar. Try typing [br]in (1,1). Next (3,2). And then (5,3). See how the points are plotted? [br]Also note that the points are alphabetically labelled with capital letters. [br]Next, type in: FitLine(A,B,C) to draw the graph. See how the equation of the line is also generated.
