can someone explain the whole Y intecept and x intercept thing to me....i just don't get it...?

Answer 1

What about it exactly? Y intercepts are where on a graph the line (or parabola, hyperbola, etc.) intersects the y axis, there can be more than one. X intercepts are where on a graph the line (Same as earlier) intersects the X axis, again there can be more than one.

Answer 2

Intercept of a graph is where it crosses either the x or y axis.

X-intercept means that the data point is at y=0...(x, 0)
To find the x-intercept from an equation, you will set y=0 and then solve for x.

Same is true for y-intercept. You will set x=0 and then solve for y.

Answer 3

Y intecept => let x= 0 in equation
x intercept => let y= 0 in equation

Answer 4

I'll try and give a really basic definition, instead of all the math gobaldigoog...

Well bascily the y-intercept is the bit of the curve/diagonal/straight line that touches the y-axis (the line with numbers on which goes upwards and is vertical). It can be written as x=0, becuase if you look down to the x-axis (horizontal line), it is 0.

the x-intercept is the bit of the curve/diagonal/straight line that touches the x-axis (the line with numbers on which goes sideways and is horizontal). It can be written as y=0, becuase if you look left/right to the y-axis (vertiical line), it is 0.

Answer 5

Intercepts are the points where the equation crosses the two coordinates axes.

example: you want to graph the equation

y = x -1

let's find the intercepts.
1) y =0 -----> x -1 =0 ----> x =1

we have the 1st intercept point (1,0)

2) x =0 ---> y =-1 ----> we have the second intercept point ( 0, -1)

if you join these 2 points , you get the graph of the equation y = x-1

****************
Intercepts are much useful when dealing with higher order polynomials, transcendental equations, etc...

Answer 6

The y-intercept is a point that intersects the y-axis and in a ordered pair it looks like this (0,Y), where y is a variable for the y-cooridinate. The x-intercept intersects the x-axis and in a ordered pair it looks like this (X,0), where x is a variable for the x-cooridinate.

Answer 7

Example
y = 3x + 6 is equation of a straight line.

Cuts y axis when x = 0 ie at y = 6
y = 6 is then the y intercept.

Cuts x axis at y = 0 ie at 3x + 6 = 0
ie at x = - 2
x = - 2 is then the x intercept.

Hope this helps.

Answer 8

y and x intercepts are where the line crosses the quadrant line. pretty much, when y=0, that is the x intercept, or where the line meets the horizontal border. when x=0, that is where the line crosses the vertical border

Answer 9

y intercept is the one on the y axis and the points are (0,x)
x intercept is the one on the x axis and the points are (x, 0)
