What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

How can you identify the slope from a graph?

Back

The slope can be identified by determining the rise over run between two points on the line.

How do you find the y-intercept from a table of values?

Back

The y-intercept can be found by identifying the value of y when x is 0.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
