Question

Which points are solutions to the equation y= 3x + 5?Select all that apply

Answer 1

In order to find the points that are solutions to this equation, let's use the x-coordinate of each point and check the corresponding y-coordinate:

`\begin{gathered} x=-3\colon \\ y=3\cdot(-3)+5=-9+5=-4 \\ \\ x=7\colon \\ y=3\cdot7+5=21+5=26 \\ \\ x=2\colon \\ y=3\cdot2+5=6+5=11 \\ \\ x=-7\colon \\ y=3\cdot(-7)+5=-21+5=-16 \\ \\ x=-2\colon \\ y=3\cdot(-2)+5=-6+5=-1 \end{gathered}`

Therefore the correct options are the third and fourth ones.
