Answer:
-2/3
Explanation:
slope = rise/run
First find the y-intercept (point of crossing on the y-axis (the vertical one)), then find the next point that intercepts a box PERFECTLY, this next point is (4, -2)
Looking at the y-intercept's coordinates (0,1), count how many blocks down it takes to get to to 4 (2 blocks which is the RISE) and now count how many blocks to the right it takes to get to -2 (3 blocks)
Therefore it is 2/3 but it is also negative because it is going DOWN from left to right which is a negative decine
