Combine like terms, 1)c+19-4 2)m+12-10

1) Would be c+15 because you can combine 19-4

2) Would be m+2 because you can combine 12-10

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
