Question

Which point is NOT on the line y = 5x + 1?

(1, 6)

(2, 11)

(0, 1)

(-1, 6)

Answer 1

To find which point is NOT on the line y = 5x + 1, we just need to plug each point into equation y=5x+1 to see which one point satisfies this equation.

check for (1,6)

y=5x+1

or 6=5*1+1

or 6=5+1

or 6=6

Which is TRUE.

--------

check for (2,11)

y=5x+1

or 11=5*2+1

or 11=10+1

or 11=11

Which is TRUE.

--------

check for (0,1)

y=5x+1

or 1=5*0+1

or 1=0+1

or 1=1

Which is TRUE.

--------

check for (-1,6)

y=5x+1

or 6=5*(-1)+1

or 6=-5+1

or 6=-4

Which is FALSE.

--------

Since only point (-1,6) fails to satisfy the given equation hence point (-1,6) is the final answer.
