Y-Intercept: equations, graphs, tables

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph. It is the value of y when x is 0.

Front

How do you find the y-intercept from an equation in slope-intercept form?

Back

In the slope-intercept form of a line, y = mx + b, the y-intercept is represented by 'b'.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where 'm' is the slope and 'b' is the y-intercept.

Front

If the slope is 2 and the y-intercept is 5, what is the equation of the line?

Back

y = 2x + 5

Front

What is the y-intercept of the line y = -3x + 7?

Back

The y-intercept is 7.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

How can you determine the y-intercept from a graph?

Back

You can determine the y-intercept by locating the point where the line crosses the y-axis.

Front

What is the y-intercept of the line represented by the equation y = 0.5x - 4?

Back

The y-intercept is -4.

Front

If a line has a y-intercept of -2, what does this mean?

Back

It means that the line crosses the y-axis at the point (0, -2).
