Interpreting Linear Graphs

Front

What is the y-intercept in a linear graph?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is 0.

Front

How do you find the y-intercept from a linear equation?

Back

To find the y-intercept, set x to 0 in the equation and solve for y.

Front

What does a positive slope indicate in a linear graph?

Back

A positive slope indicates that as x increases, y also increases.

What is the formula for calculating the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

What is the significance of the x-intercept in a linear graph?

Back

The x-intercept is the point where the line crosses the x-axis, representing the value of x when y is 0.

How can you determine the x-intercept from a linear equation?

Back

To find the x-intercept, set y to 0 in the equation and solve for x.

Front

What does it mean if a line is horizontal in a graph?

Back

A horizontal line has a slope of 0, indicating that y remains constant regardless of the value of x.

What does it mean if a line is vertical in a graph?

Back

A vertical line has an undefined slope, indicating that x remains constant regardless of the value of y.
