Hi can you please help me with this question step by step thank you

4. a) Graph the line defined by the equation r = [2,1] + s[-2,5], s E R on the grid below (or neatly on graph paper with labelled axes). Be sure to label each line graphed. b) On the same set of axes, graph the line q = [-2,1] + t[2,1], t E R. Y -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 X c) Determine an equation for the line that is perpendicular to r in vector form. Call it p. d) Write lines r and q in y=mx+b form. 5. In every line above in vector form we notice we have a statement showing that the parameter is in the real number system (t E R). Explain what would be graphed if, instead, the restriction on the parameter is that it is in the integer number system (t E Z). Include a brief sketch of a graph that would be produced. An example of this is v = [1,2] + t[3,4], t E Z. The Z denotes the integer number system
