Answer:
Step-by-step explanation:
1.
(-2,0) (0,-7) y2-y1
-----------------
x2-x1
-7-0= -7
0- (-2)= 2 ------>>> -7/2 =m or slope
2.
y= -7/2x+b to find b u plug in one pair of coordinates for example (-2,0)
and use inverse properties to find b
0 = -7/2(-2) + b
14/2 = 7
0= 7+b
-7 -7
-----------
-7=b
3.
y=-7/2x-7
You can you 72 which would make 2/8 18/72 and 3/9 24/72 which makes the sum 42/72.

Answer: L=90-10t
0-90
1-80
2-70
3-60
Step-by-step explanation:
that should be right lol
because it decreases by ten a week so just count down by ten each week. Then, you can make the equation 90-10t and if you substitute each week for t it is true.
90-10(0)=90-0=90
90-10(1)=90-10=80
and so on...
