Question

Which points are solutions to the equation y = 6x - 4?Select all that apply.(-3, -14)(3, 14)(-2,-16)(0-4) (-2.16)

Answer 1

Given:

$y=6x-4$

Substitute the point (-3,-14)

$\begin{gathered} -14=6(-3)-4 \\ -14=-18-4 \\ -14\ne-22 \end{gathered}$

Substitute the point (3,14)

$\begin{gathered} 14=6(3)-4 \\ 14=18-4 \\ 14=14 \end{gathered}$

Substitute the point (-2,-16)

$\begin{gathered} -16=6(-2)-4 \\ -16=-12-4 \\ -16=-16 \end{gathered}$

Substitute (0,-4)

$\begin{gathered} -4=6(0)-4 \\ -4=-4 \end{gathered}$

Substitute (-2,16)

$\begin{gathered} 16=6(-2)-4 \\ 16\ne-16 \end{gathered}$

Points (3,14),(-2,-16) and (0,-4) are the solutions of the equation.
