What is the point-slope form

The table shows values for functions f(x) and g(x) . x f(x)=3x g(x)=2x+1 −2 19 −3 −1 13 −1 0 1 1 1 3 3 2 9 5 what is the solution to f(x)=g(x) ? select each correct answer.

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

This is different from the first one can someone me
