Answer:
Step-by-step explanation:
y=mx+b
so inset the first point into the equation
-3 for x and 7 for y.
7=m(-3)+b
y=mx+b
1 for x and -1 for y
-1=m(1)+b
now put them together and solve for m and b.
-1=m+b
7=-3m+b
--------------------
-1-b=m
7=-3m+b
inset m into the equation
7=-3(-1-b)+b
7=3+3b+b
4=4b
b=1
--------------
insert b back in for -1=m+b
-1=m+1
m=-2
---------------------------------------
Now insert it back into y=mx+b
y=(-2)x+1
so this line contains those points that were given
Hope this helps :)
Answer:
36 crackers
Step-by-step explanation:
If he normally eats 8 crackers every weekday, he consumes about 40 crackers.
On the last day however, he dropped 4, so he only ate 4.

Answer:
the total distance walked is 20 km
Step-by-step explanation:
The computation of the total distance he walked is shown below:
Let us assume the total distance walked be d
Now the total time would be
Total time = (d ÷ 2) ÷ 8 + (d ÷ 2) ÷ 5 = 3.25
d ÷ 16 + d ÷ 10 = 3.25
(5d + 8d) ÷ 80=3.25
13d = 260
d = 20 km
Hence, the total distance walked is 20 km
