Iwant to know what this question is asking me to do mathematicaly and how to do it

Draw y = -1/2x + 4 on the graph because it’s already converted into y = mx + b form. And then for the other one you get y = 1/4x + 1 and you have to graph that too! Remember rise over run too, but idk if your teacher taught you that.

C. expression because any expression or equation may contain more than one variable
