Coefficient: 20 or 5
Variable: c or w
Constant: 95.50
Pt B: 20(5) + 5(20) + 95.50
100 + 100 + 95.50
295.50
Pt C:The coefficient of c would change to 10

Answer:
The answer to your question is the letter B) y = 3x - 3
Step-by-step explanation:
Data
Point = (2, 3)
slope = m = 3
Process
To solve this problem just substitute the values given in the slope-point equation.
Formula
y - y1 = m(x - x1)
x1 = 2 y1 = 3
-Substitution
y - 3 = 3(x - 2)
-Expand
y - 3 = 3x - 6
-Solve for y
y = 3x - 6 + 3
-Result
y = 3x - 3
Given:
The table of values.
To find:
The y-intercept of the given function.
Solution:
The table of values represents a linear function because the rate of change is constant.
Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is





Adding 15 on both sides, we get


Putting x=0, we get



The y-intercept is 9. Therefore, the correct option is C.
