Answer:
-2
Step-by-step explanation:
find rise over run with y1-y2/x1-x2 = -2/1 = -2
20 jumps because 45/20 is 2.5 and 8 x 2.5 is 20.
Step-by-step explanation: First you convert the equation into standard form, which is y=mx+b . Then graph it. When it is in the form y=mx+b it is easier to graph. Then you can see the intercepts on the graph and come up with your answer.
Hope this helps!
You need to simplify it first.
Use distribution
y=mx+b
m=slope
your slope is -4 :)
