Answer:
b = -4
Step-by-step explanation:
In y =mx+b form, the y-intercept is b, which in this case is -4.
The power of the input variable, x, of the function is 1, therefore, the
function is a linear function.
Correct response:
- The y-intercept is -4
Method used to find the y-intercept
The function defining the line is; y = 6·x - 4
The function is a linear equation of the form; y = m·x + c
Where;
m = The slope
c = The y-intercept
By comparison, we have;
- The y-intercept of the straight line function; y = 6·x - 4 is -4
The y-intercept can also be obtained as follows;
The y-intercept is the value of the function when x = 0
Therefore;
- y-intercept = y = 6 × 0 - 4 = -4
