and this problem were asked a graph of function given the ex otherwise equal to two. First. Let's see you write this equation. Families playing both sides by why, on dividing both sides by two to give us a function wise equals a to X. Now we can graft this function when Mexico says zero y is equal to zero when X is equal to two, why sequels before and so on. This will give us a linear function. Now we need to determine if this function is a direct variation. The function is a direct variation when it does a linear function that is 1 to 1, as we determined in part A. This is a linear function, and that's because the ratio between these two variables is a constant constant equal to two. So this is a direct variation. All in your functions are direct. Very are our 1 to 1. But we can also see this by using the horizontal line test. No matter where we draw a horizontal line, our graph will only intersect the horizontal blind at one point, so this function is 1 to 1
