What is the equation of the following line written in general form? (The y-intercept is -1.).
1 answer:
Answer:
The answer is C.
Step-by-step explanation:
In the graph above, it is a positive gradient so option A and B cannot be applied.
Next you have to look at the y-intercept where the line touches the y-axis so -1 is the y-intercept.
The slope-form equation is y = mx + b where m represents gradient amd b is y-intercept :
Option A,
Option B,
Option C,

If f(x) = (6x-11), then f(-6) = -47.
We are provided in the question statement with a function "f(x)" whose output is a polynomial of 1 variable and degree 1.
To obtain the value of f(-6) from the output polynomial of the function f(x), we will simply need to substitute (-6) as the value of x in the polynomial and calculate the final value.
So,
Hence, f(-6) = -47.
- Polynomial: In mathematics, an expression of more than two algebraic terms, especially the sum of several terms that contain the same variable(s) of different powers and individual, distinct co-efficients.
- Function: In Mathematics, a function is an operator which on taking input, provides a certain output.
