this question asks us to determine the slope and the Y intercept of this graph here, and we should remember that the standards slope formula is MX plus B where these are, Why intercept and M is our slope and we can figure out be just by looking after graph now. So he's wherever a point lies on the why access. And we see this point right here about the middle of the graph and that gives us the coordinates zero comma one. And now we can figure out the slope of the graph. You can either algebraic glee, a subtracted points or, if you want to count the graph, rise over run. We can do that and I'll show you both methods. So if we're doing rise over one run will notice that we go up one and over one to get to one point. And then again, we go up one and we go over one and again we go up one and over one. So we have rise overrun, and we always get 1/1. So we know where slope is going to be. One algebraic lee, if you want to solve it. If you don't feel comfortable counting the graph. You can figure out slope with y tu minus one by one over X two minus X one. And we can use the point here. So we have zero comma one, Let's say that X two and why to. And then we can use this point here, which is one common to and we can say that this is X one and why one it's now we can plug these points into the scrap here where this formula here. So why to we have listed as one? Why one we have listed as to and X two. We have listed at zero x one we have listed as one. So we get one minus two gives us minus 10 minus one gives us minus one, which simplifies toe one. So if we go back to this formula here, why equals we have our slope that we determine both graphically and algebraic Lee to be one. So you can write that as X and our B we see from here is this Why intercept point plus one. So X plus one is the slope
