Answer:
Graph 1
Step-by-step explanation:
I can help you better understand this topic. a proportional graph is a straight line. a liner proportional graph goes through the orgin. a non linear does not. so your equation is Y=mx+b . remember your b is where it cuts the axis. In your final answer you always leave out the y value and x value. if they is a b you pick a y . solve for m. multiply m to x value. the x value is the corresponding value to the y one. and you subtract b from y. in your final answer you write y=1x+4 or something like that. that is just an example. If they is no y interpret or b you pick 2 y values make a line on your paper put y value first that is higher on the coordinate grid then you subtract the other y from that. you do same thing with corresponding x value. Remember y over x. you simply your answer and that is your m. you pick a y value. your corresponding x value will be multiple to m. so your equation is Y=mx for example your equation could be y=5x. Hope this helps.
