y=mx+b is the formula
-
with the point you have, solve for b
--
-6=2/3(1) + b
b = -20/3
---
y = 2/3x - 20/3

im just reduing it to make it more understandable
y=mx%2Bb slope- intercept formula
y=%282%2F3%29x%2Bb plugged in slope (2/3)
-6=%282%2F3%291%2Bb plugged in point (1,-6)
-6=2%2F3%2Bb subtract 2/3
-6-2%2F3=b add like terms
-20%2F3=b
.
rewrite the formula with slope (m) and intercept (b)
highlight%28y=%282%2F3%29x-20%2F3%29
