Finding the coordinates of a point on a graph

Step 1: Calculate conversion coefficients for converting screen pixels to the graph’s units

(a) Click a point with known coordinates on the y-axis, then enter its (x,y) coordinates

x:

y:

Is the y-axis on a logarithmic scale? Please enter 1 for “Yes”, or 0 for “No”:

(b) Click a point with known coordinates on the x-axis, then enter its (x,y) coordinates
