Question 181407
I am not sure what you mean by you added an x-factor, I hope this point (2,4) was also given to you....if so .....

Concept you should know:

(1)coordinate point (x, y)

(2)slope=m= change of y/ change of x = (y2-y1)/(x2-x1)
***********************

Your points:

point 1 = (0, 3) = (x1, y1)

point 2 = (2, 4) = (x2, y2)

m= (y2-y1)/(x2 - x1)
m= (4 - 3)/(2 - 0)
m= 1/2
