Question

does the point (3,2) lie on the line 2x+5y=4? im guessing its yes(teacher told us) but im getting -2=0??

Answer 1

when you input the values (x=3; y=2) into the equation; does it equal 4?

Answer 2

2(3) +5(2) ?= 4

6 + 10 ?= 4

16 ?= 4 ...false

Answer 3

well i get y=-2/5x-4/5 then i plug it in

Answer 4

why go thru the hassle of rearranging an equation? the results are the same no matter how you do it; so far as you do it correctly that is :)

Answer 5

2x+5y=4

y = (-2/5)x + 4/5
