Daniel wants to predict how far he can hike based on the time he spends on the hike. he collected some data on the time (in hours) and distance (in kilometers) of some of his previous hikes. a line was fit to the data to model the relationship.

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
