(MCA) 4.2 Graphing using x and y intercepts.

Front

What is the y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis, represented as (0, y).

Front

How do you find the x-intercept of a linear equation?

Back

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

Front

What is the x-intercept of the equation 3x + 8y = 24?

Back

(8, 0) is the x-intercept.

Front

What is the y-intercept of the equation 3x + 4y = 24?

Back

The y-intercept is (0, -6).

Front

What does the x value of the y-intercept always equal?

Back

The x value of the y-intercept is always 0.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By = C.

Front

How can you graph a linear equation using intercepts?

Back

To graph using intercepts, find the x-intercept and y-intercept, plot them, and draw a line through both points.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction of the relationship between x and y.

Front

What is the formula to calculate the slope between two points?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a linear graph?

Back

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