Write the matrix form of the function and solve:
x 1 2 y 2 5 1 1 1 = 0 2 x + 2 y + 5 − 4 − y − 5 x = 0 − 3 x + 1 + y = 0 y = 3 x − 1
#1 - 3, 1, 2
#2 - x+2y=4
#3 - y=3x-1
The equation for the relation given by the points (1, 2), (2, 5), (3, 8) is y = 3 x − 1 . This is derived from calculating the slope and y-intercept using the provided points.
