The answer is y = 2x - 3. Because you'll first start a point -3. Now 2x would change and add an invisible on making it 2/1. Then from point -3. You'll rise up 2 units and run 1 unit to the right. Showing exactly in the graph.
You start at the point -3. THen as you find the y value you will go up by two units and then go 2 units to the right. THis will give u ur answer if y=2x-3. Hope this helps!
