Final answer:
To find the values for (x1,y1) and (x2,y2) from (20,8) and (9,16), we can use the given information to solve for the missing values. From x1=20, we know that y1=8. To find x2, we can use the equation (x1,y1) = (20,8) and plug in the values for x1 and y1. From this, we find that (9,y2) = (9,16), so the values for (x2,y2) are (9,16).
Step-by-step explanation:
To determine the values for (x1,y1) and (x2,y2) from (20,8) and (9,16), we need to identify the x and y coordinates of the two points. Given that x1=20, the corresponding y value is y1=8. Similarly, since y2=16, we need to find the value of x2.
Using the given points, we can write two equations: (x1,y1) = (20,8) and (x2,y2) = (9,16). From equation (x1,y1), we know that x1=20 and y1=8. Plugging in these values into equation (x2,y2), we find that (9,y2)=(9,16). Therefore, the values for (x2,y2) are (9,16).
