Answer:
11y is the exact value.
Step-by-step explanation:
A. Constant of proportionality in this proportional relationship is; k=5
B. Equation to represent this proportional relationship is : c=t/k
Step-by-step explanation:
A.Given that : the amount she pays each month for international text messages is proportional to the number of international texts she sends, then
$3.20 k = 16 ---------where k is the constant of proportionality
k= 16/3.20 =5
k=5
B. Let c be the cost of sending the texts per month and t be the number of texts sent per month , so
c=t/k
c=t/5 ---------- is the proportionality relationship.
For t=16 , c= 16/5 =$3.20

Answer:
y = -5x + 7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define
5x + y = -2
Random point (2, -3)
Step 2: Rewrite
y = -5x - 2
m = -5
Step 3: Write parallel line
y = -5x + b
-3 = -5(2) + b
-3 = -10 + b
7 = b
y = -5x + 7
