The y -intercept is often referred to with just the y -value. For example, we say that the y -intercept of the line shown in the graph below is 3.5 . When the equation of a line is written in slope-intercept form ( y=mx+b ), the y -intercept b can be read immediately from the equation.
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Moreover, How do I find the Y intercept?
It’s called the “y intercept” and it’s the y value of the point where the line intersects the y- axis. For this line, the y-intercept is “negative 1.” You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
Secondly, What does the Y intercept tell me?
The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
Simply so, How do you find the Y intercept in an equation?
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
What is the Y intercept for y =- 2x?
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 0 .

How do you find the Y intercept without an equation?
How Do You Find the X- and Y-Intercepts of a Line in Slope-Intercept Form? To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’.
What is Y intercept form?
Every straight line can be represented by an equation: y = mx + b. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
What is the Y intercept in the equation y =- 2x?
Using the slope-intercept form, the y-intercept is 0 .
What is Y intercept in standard form?
The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.
What is the Y intercept of y =- 2x 6?
y-intercept: Put x = 0 in the equation y = 2x – 6 and solve for x. The y-intercept is -6.

How do you find the Y intercept when given two points?
You can find the y-intercept (which is also the ‘b’ in y = mx+b) by plugging in the y and x to y = mx+b. Of course, you don’t know what b is right now so you would put in the x and y. You would choose one of the given points.
