(Y-Y1)/(X-X1)
(-9-(-29))/(7-15)
20/-8
-2 1/2
The slope is -2 1/2
A. becuase you just follow thw number place ment and add zeros. so the firt 7 has five places behind it you jut put zeros in those plases.
You pretty much just flip the second fraction and factor
Answer:
55 +20 = 75
then she cuts 15
75-15 = 60
60 cm in milimiters
50*10
600 milimeters is the answer
Step-by-step explanation:
Answer:
3/-1
Step-by-step explanation:
the equation for slope is y2-y1/x2-x1
I chose the two points (4,2) and (0,-2) because that's where the line meets up
then I put them in the equation getting 4--2/0-2
simplifying getting you 6/-2
you can simplify more giving you 3/-1
