For each line below, determine the slope, the y-intercept, and the equation of the line. Help me please

Red:
Y-intercept= 4
Slope= 3x
Equation= m=3x+4

Blue:
Y-intercept= -4
Slope= -1/3x
Equation= m=-1/3x-4

Hope this is right and will help.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
