Question
Find the y-intercept in the following equation: y = - 4 x - 5
- - 4
- - 4 x
- 5
- - 5
Hint:
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. A linear function represents a line, i.e., its graph is a line. Here,
- 'm' is the slope of the line
- 'b' is the y-intercept of the line
- 'x' is the independent variable
- 'y' (or f(x)) is the dependent variable
The correct answer is: - 5
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. A linear function represents a line, i.e., its graph is a line. Here,
- 'm' is the slope of the line
- 'b' is the y-intercept of the line
- 'x' is the independent variable
- 'y' (or f(x)) is the dependent variable
y = - 4 x - 5 comparing with y = mx + b
Here slope of y intercept = -5.
