Which is the equation for ce?
a.) x+y=1
b.) y=4/5x+1
c.) y=4/5(x+1)
d.) y+x-1

Well, first keep in mind, (c,e) is not praportional, it does not go through the point of origin. so the thing is c=(0,1) and e=(5,5) see, not proportional. so, i might be mistaken but i think the answer is, c, i could be wrong.

B. y=4/5x+1
you can tell that the slope is 4/5 because from c to e it goes up 4 and to the right 5. both points fit into this equation

Did u want to find the value of x?
