(0,0) (4,6) first you use the equation y2-y1/x2-x1 , 6 would be y2 because it is y in the second order pair then 0 would be y1 because it is y in the first order pair and 4 would be x2 because it is x in the second order pair and 0 would be x1 because it is x in the first order pair so
at the end it should look like this 6-0/4-0. you do the top first, 6-0= 6 and 4-0 = 4
your answer should look like this 6/4 then you simplify the fraction. since they are both even numbers they simplify into 2.
so 6 divide by 2 and 4 divide by 2 and your answer 3/2
