What does the y-intercept represent?

Definition of y-intercept

: the y-coordinate of a point where a line, curve, or surface intersects the y-axis.

What is the y-intercept and what does the y-intercept represent?

The y intercept is the point where the line crosses the y axis. If given the line in slope intercept form y = mx + b, the y-intercept would be the point (0,b), because the y-axis is at x = 0.

What is the y-intercept examples?

When the equation of a line is written in slope-intercept form (y=mx+b), the y-intercept is the constant, which is represented by the variable b. For example, in the linear equation y=4x−5, the y-intercept is −5.

What does the y-intercept mean in real life?

Just like the slope of a line, many algebra classes go over the y-intercept of a line without explaining how to use it in the real world. The y-intercept of a line is the value of y where the line crosses the y-axis. In other words, it is the value of y when the value of x is equal to 0.

What is the meaning of the y-intercept in linear regression?

The constant term in linear regression analysis seems to be such a simple thing. Also known as the y intercept, it is simply the value at which the fitted line crosses the y-axis. … That’s not surprising because the value of the constant term is almost always meaningless!

What is the y-intercept of y =- 3?

Algebra Examples

Using the slope-intercept form, the y-intercept is −3 .

What is the y-intercept when 3x 2y =- 6 is graphed?

Solution: To find the y-intercept of 3x + 2y = -6, let x = 0. y = -3 The y-intercept is -3.

What is the y-intercept of the function f x 2 9x 1 3?

1/3
Summary: The y-intercept of the function f(x) = -2/9x + 1/3 is 1/3.

What is y-intercept of 4?

Using the slope-intercept form, the y-intercept is 4 .

What is the y-intercept of 0 4?

Since the y intercept is (0, 4), b = 4 and the slope, m, is given as 2/3.

What is the y-intercept of the line 2?

-2
y=−2 is a flat line crossing the point at (0,−2) therefore the gradient is zero and the the y intercept is -2.

What is the y-intercept of y =- 9?

Using the slope-intercept form, the y-intercept is 9 .

What is the y-intercept of y 2x 5?

In the equation y = 2x – 5, the y- intercept, b, is –5. This means the line crosses the y-axis at –5.

What is the y-intercept of y =- 3x?

Using the slope-intercept form, the y-intercept is 0 .

What is the y-intercept of y =- 9x?

Using the slope-intercept form, the y-intercept is 0 .

What is Y =- 1 in slope-intercept form?

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the y-intercept is −1 .

What is the slope of y =- 9x?

−9
Slope is −9 , y-intercept is 0 and x-intercept is 0 .

What is the y-intercept of Y 9x 5?

Pre-Algebra Examples
