Answer:
y = 1/9x +10
Step-by-step explanation:
It is convenient to start with a version of point-slope form and simplify the result.
y = m(x -h) +k . . . . . line with slope m through point (h, k)
Using the given numbers, we have ...
y = (1/9)(x -18) +12
y = 1/9x -2 +12 . . . . . eliminate parentheses
y = 1/9x +10
