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 line?

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 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line, which means the y-value remains constant regardless of the x-value.

Front

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

Back

To find the y-intercept on a graph, look for the point where the line crosses the y-axis.

Front

What does a negative y-intercept indicate about a line?

Back

A negative y-intercept indicates that the line crosses the y-axis below the origin (0,0).

Write the equation of a line with a slope of 2 and a y-intercept of -3.

Back

y = 2x - 3
