To determine which ordered pair forms a proportional relationship with the given points, we need to check if the ratio of y-values to x-values remains constant.
Let's calculate the ratio for each option:
1. (10, 10): y-value/x-value = 10/10 = 1/1 = 1
2. (25, 35): y-value/x-value = 35/25 = 7/5 = 1.4
3. (70, 50): y-value/x-value = 50/70 = 5/7 ≈ 0.714
4. (90, 60): y-value/x-value = 60/90 = 2/3 ≈ 0.667
The only ordered pair with a constant ratio (approximately 1) is (10, 10). Therefore, (10, 10) forms a proportional relationship with the given points (0, 0) and (45, 30).
