Respuesta :
If you know the ratio between a and b, assign the value of a to x and b to y.
You set the slope as b/a. The equation of the line would be y = (b/a)(x)
Any point on the line (besides the origin) would be an equivalent ratio (a:b would be x:y)
Answer: Plot the ordered pairs (2, 5) and (4, 10). Start at (4, 10). Move right 2 and up 5, and then plot a point. Use the same rate to plot other points. You could also draw a line through the origin and the two given points. Any point on the line represents an equivalent ratio.
