Finding Y-Intercept (11:30)

Front

What is the meaning of the y-intercept?

Back

The y-intercept is the value of y when x is 0 in a linear equation or graph. It represents the point where the line crosses the y-axis.

Front

What is the y-intercept in the table with points (-1, 9), (1, 1), (0, 5), (5, 0)?

Back

(0, 5) is the y-intercept, as it is the point where x equals 0.

Front

What is the y-intercept in the equation y = -2x + 5?

Back

The y-intercept is 5, which is the constant term in the equation.

Front

What is the y-intercept of a linear graph that crosses the y-axis at -3?

Back

The y-intercept is -3.

Front

What is the y-intercept of the line graphed below that crosses the y-axis at 4?

Back

The y-intercept is 4.

Front

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

Back

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

Front

What does a positive y-intercept indicate about a linear graph?

Back

A positive y-intercept indicates that the line crosses the y-axis above the origin.

Front

What does a negative y-intercept indicate about a linear graph?

Back

A negative y-intercept indicates that the line crosses the y-axis below the origin.

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept of the line.

Front

If a line has a y-intercept of 0, what does this mean?

Back

It means the line passes through the origin (0,0).
