Answer:
y = dependent variable
k = constant of proportionality or constant rate of change
x = independent variable
Step-by-step explanation:
The equation,
represents a direct variation showing a proportional relationship between variable y and variable x.
y represents the dependent variable
k represents the constant of proportionality or constant rate of change
x represents the independent variable
Answer:
x = -2, y = 5.
Step-by-step explanation:
y=−4x−3
y=−2x+1
Because y is common to both left sides:
-4x - 3 = -2x + 1
-4x + 2x = 1 + 3
-2x = 4
x = 4/-2
x = -2.
So y = -4(-2) - 3
= 8 - 3
= 5 .
