identify two points that lie on this line

jimthompson5910 (jim_thompson5910):

tell me what they are

OpenStudy (anonymous):

(1,4) (2,-3)?

jimthompson5910 (jim_thompson5910):

you have the coordinates backwards

OpenStudy (anonymous):

oh so 4,1 and -3,2?

jimthompson5910 (jim_thompson5910):

better

jimthompson5910 (jim_thompson5910):

now what you can do is for each answer choice, you plug in each point and see which point makes the equation true

jimthompson5910 (jim_thompson5910):

for choice A, the equation is 20 = 2x - 13y plug in (4,1) to get 20 = 2x - 13y 20 = 2(4) - 13(1) 20 = 8 - 13 20 = -5 the last equation is false, so (4,1) is NOT on the line 20 = 2x - 13y

jimthompson5910 (jim_thompson5910):

so that rules out choice A
