Answer:
y = 3x + 3
Step-by-step explanation:
Given parameters;
Coordinates of the line;
(-2, -3)
Slope of the line = 3
Unknown:
Equation of the line = ?
Solution:
The equation of any straight line is often expressed as;
y = mx + c
y and x are the coordinates
c is the intercept
Now insert values of y, x and m to find c;
-3 = 3(-2) + c
-3 = -6 + c
c = -3 + 6 = 3
The equation of the line is;
y = 3x + 3
Domain :
Range:
Step-by-step explanation:
The function is
The domain of a function is the set of real numbers. Since, the function has no undefined points, the domain of the function is the set of all real numbers.
Hence, the domain of the function is
The range of a function can be found be substituting the values for x, the corresponding y-values can be determined.
Hence, the range of the function is
