Answer:
For a ) y = 6x - 3
For b ) y = -2x - 10
For c ) y = -4x + 4
Step-by-step explanation:
Given:
a. y = 6x - 3
b. y = -2 (x + 5)
y = -2x - 10
c. y = 4 (-x + 1)
y = -4x + 4
To Find:
y-intercept and the slope for each equation = ?
Solution:
Slope-intercept Formula is given by
Where,
m = slope
c = y-intercept
So on comparing the Given equations with the above Equation we get
For a ) y = 6x - 3
For b ) y = -2x - 10
For c ) y = -4x + 4
In the equation 
, a is the initial amount and b is the growth factor. So our initial amount is 30 and our growth factor is 8.3. Your correct choice for this is A.
