Question
Determine the slope and y-intercept from the following equation: y = 
x + 3
- Slope: 5 y-intercept: (0,3)
- Slope: y-intercept: (0,3)
- Slope: 4 y-intercept: (0,3/2)
- Slope:
y-intercept: (0,5)
y-intercept: (0,3) y-intercept: (0,5)
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: Slope: y-intercept: (0,3)
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 following equation: y = x + 3 comparing with y = mx + b
Thus, Slope: y-intercept: (0,3)
