SOLUTION: Please help me solve this: Find the missing coordinate in the following solution for y=-4x+2:(-1,?) Thanks

You can put this solution on YOUR website!
Coordinates come in the form (x,y).
If your x is -1, you must plug it into wherever you see it in the equation.
y = -4x + 2
y = -4(-1) + 2
Solving the second line will give the solution.
y = -4(-1) + 2
y = 4 + 2 <<< Negative one times negative four gives us positive four.
y = 6 <<< Add the two together.
Your 'y' coordinate is six, giving you (-1,6).
