[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{(12 - 9)}{(1 - 4)} = \frac{3}{( - 3)} = - 1[/tex]
So the slope/gradient = -1
Answer:
-1
Step-by-step explanation:
if you get a piece of graph paper and graph the points you can then figure out the rise over run. to do this you just figure out how many squares for the rise/run it take to get to the next point. for example to get to the next point in this problem you would go down three squares and then over three squares, so the rise over run would be -3/3 then you reduce that to its simplest form and you have your slope (-1).
