Presumably because the lines are plotted on the Cartesian plane. So the line intersects the y-axis at the point (0, y).
The standart form of the equation of a line is y = ax + bx + c. If you replace x with 0, then y = c. Thus, the y-intercept point is (0, c).

What is the slope and y intercept for y - x equals 0?
y - x = 0 which is the same as y = x + 0 which is of the form y = mx + c where m is the slope and c is the intercept. Hence for y = x + 0, the slope is 1 ans the intercept is 0. The equation represents a line making 45 degrees to the a-axis and it passes through the origin.
What form of a quadratic function would be graphed having the vertex at the same point as the y- intercept?
The function would be in the form of ax2+c. The axis of symmetry would be the y-axis, or x = 0, because b would be zero. Likewise, the y-intercept is not important, as any value of c will still yield a vertex at the y-intercept.
How do you find the y-intercept of a linear relationship from a graph?
To find the y-intercept from a graph - look at where the graph of the line intersects the y-axis. The point at where the graph of the line crosses the y-axis will be the y-intercept with the coordinates of (0,y) The point at which the line cuts the y – axis is called as y – intercept.You can locate the point by seeing the graph.Note:If you are given a linear equation say ax + by + c = 0Now if we plug x = 0 in the given equation we will get the y – intercept.y = -c/bIf the given equation is of the form y = mx + bb is the y – intercept of the line.

Find the inercept of the line 3x-6y equals 12?
The standard equation of a straight line in the slope-intercept form is y = mx + c where m is the slope and c is the y intercept.3x - 6y = 12 can be re-written as 6y = 3x - 12 or y = 1/2x - 2.-2 is therefore the y intercept (this is when x = 0)The x intercept (when y = 0) can be obtained from the equation y = 1/2x - 2 : 0 = 1/2x - 2 : 1/2x = 2 : x = 4.
If the slope of a line is 4 and the y intercept is negative 2 what is the linear equation in the slope intercept form?
slope intercept form is y=mx+b (m is slope, b is y intercept) slope = 4, y intercept = -2 y = 4x -2
How do you figure out the y intercept in slope intercept form?
The slope intercept form is y = mx + c where the coefficient of y must be 1. Then c is the y-intercept ie the point (0,c) lies on the line.
How do you find y-intercept?
The y-intercept can be obtained from the straight line formula, y=mx+c. The y-intercept, c, is therefore given by c=-mx+y where m is the coefficient of gradient.
What is intercept form for a equation of a line?
The slope-intercept form is y = mx + c where m and c are constants. The y-intercept is (0,c).
How do you write slope intercept form?
y = mx+c where m is the slope and c is the y intercept
What is important about the y intercept?
The y-intercept is where a graph cuts the y-axis. (When the x coordinate = 0) All linear graphs can be expressed in the form y = mc + c where m is the gradient and c is the y - intercept.
What is an constant term in math?
The y-intercept. Ex: AX-BY=C The 'C' stands for constant and is the y-intercept. Was this helpful?
How do you find the y-intercept of a linear equation?
First write it in the "slope-intercept" form : y = mx + c Then the y-intercept is (0, c)
How do you find the intercept of a line?
The y-coordinate of the point where the line cuts the y-axis If the line can be represented as y = mx + c, then c is the intercept
Find the y-intercept of the function y equals 2x - 8?
-6
How do you find slope and y-intercept of a line?
By using the straight line equation of y = mx+c whereas m is the slope and c is the y intercept
Which of the following is the slope-intercept form of the equation?
The slope-intercept form of the equation is y = mx + b, where m represents the slope and b represents the y-intercept. It is used to graph linear equations easily.
How do you find the and y intercept to x plus y equals 6?
Rewrite it in the form y = mx + c and then the y-intercept is c.So x + y = 6 => y = -x + 6 Therefore [m = -1] and c = 6 so the y-intercept is 6.
