Answer:
Slope = - 1
Step-by-step explanation:
The equation is in form
,
s the slope and
is the intercept on
axis.
Hence, in
, slope is -1 and intercept on
axis is 3.
It's a linear function: y = mx + b
We have (138; 112.96); (209; 142.78)
substitute the values of x and y to the formula of slope m:

Now we have: 
We must find b. Substitute the value of x and y from first pair of numbers:

Answer: y = 0.42x + 55
Answer:
The other number is 70.4
Step-by-step explanation:
176 ÷ 2 = 88
88 - 20% = 70.4
20% of 88 is 17.6
88 + 17.6 = 105.6
105.6 + 70.4 = 176
Answer:
I would think multiply
Step-by-step explanation:
I'm not sure but I dont think I see the whole problem
Answer:
A dilation factor by 1/2
Step-by-step explanation:
Find the distance of AB and BC which is 4 for each of them. A'B' and B'C' distance is 2. 4 * 1/2 = 2. Therefore the answer must be 1/2.
