Question

Which of the following is the equation of a line that passes through the origin?
a. y=4/5x+8
b. y=x-1/5
c. y=4/3x
d. y=-7x+3

Answer 1

the answer is c) because the origin is (0,0) and all you have to do is sub in x=0 and y=0 into each of them and identify if the equation is true or not.
y=4/3x
0 = 4/3(0)
0=0
so it is correct.
