0, 17447
4, 21189
---
to solve the linear equation, copy and paste this (the two given points):
0, 17447, 4, 21189
into the "Two-Point form: x1 y1 x2 y2" input box here: https://sooeet.com/math/linear-equation-solver.php

answer:
x-intercept = (-18.6499198, 0)
y-intercept = (0, 17447)
slope = 935.5
---
the slope-intercept form:
y = 935.5x + 17447
---
average annual rate of increase for room, board and tuition is: $935.50
