To determine who was faster, we need to compare the rates of movement of both individuals.
For the first guy, we have the equation: y = -3.5x + 7.
This equation represents a linear function in the form of y = mx + b, where m represents the slope or rate of change.
In this case, the slope is -3.5, indicating that for every 1 unit increase in x, the y-value decreases by 3.5.
Therefore, the rate at which the first guy is moving is -3.5 distance/second.
For the second guy, it is given that he is moving at a constant rate of 3.5 distance/second.
Comparing the rates, we can conclude that the second guy was faster as his speed of 3.5 distance/second is greater than the first guy's rate of -3.5 distance/second.
Two people were in a race. The first guy moved (y = -3.5x + 7), while the second guy moved 3.5 distance/second. Who was faster?
