What is the slope of the line represented by the equation $$y = 2x + 3$$ ?

The slope of the line is $$2$$ .

What is the slope of the line represented by the equation $$y = -\frac{1}{2}x + 4$$ ?

The slope of the line is $$-\frac{1}{2}$$ .

How can you determine the slope from two points (x1, y1) and (x2, y2)?

The slope can be calculated using the formula $$m = \frac{y2 - y1}{x2 - x1}$$ .

What is the slope of the line represented by the equation $$y = 3x - 4$$ ?

The slope of the line is $$3$$ .

What is the y-intercept of the line represented by the equation $$y = -4x + 2$$ ?

The y-intercept of the line is $$2$$ .

If a line has a slope of 0, what does that mean?

A slope of 0 means the line is horizontal and does not rise or fall as it moves along the x-axis.

If a line has an undefined slope, what does that mean?

An undefined slope means the line is vertical, and it does not have a defined rise over run.

What is the slope and y-intercept of the line represented by the equation $$y = -\frac{1}{4}x + 2$$ ?

The slope is $$-\frac{1}{4}$$ and the y-intercept is $$2$$ .

How do you write the equation of a line given the slope and y-intercept?

The equation can be written in slope-intercept form as $$y = mx + b$$ , where $$m$$ is the slope and $$b$$ is the y-intercept.

What is the significance of the slope in real-world applications?

The slope can represent rates of change, such as speed, growth, or decline, in various real-world contexts.
