When the y-intercept of a line is 0 the relationship is what?

A horizontal line (other than y = 0) will not have an x-intercept. The line y = 0 is another special case since y = 0 is the equation of the x-axis. The y-intercept will always be the number in the equation.

What happens when y equals 0?

Since the equation y = 0 has a y-intercept of 0, your graph is essentially the x-axis. The y-value is always 0.

Is y-intercept always 0?

The Y intercept of a straight line is simply where the line crosses the Y axis. The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..

Which relationship has a zero slope?

A line with zero slope is horizontal. A line with infinite slope is horizontal.

Which line has a slope of 0?

horizontal line
A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

Can you have a y-intercept of 0?

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

How do you find the y-intercept when y is 0?

College Algebra

  1. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
  2. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
  3. To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

What if there is no y-intercept?

If a line has no y-intercept (that is, it does not cross the y-axis) it must be vertical, parallel to the y-axis, with an equation like x=k1. Similarly, if it has no x-intercept, a line must be horizontal, with a slope of zero, parallel to the x-axis, with an equation like y=k2.

Is the y-intercept at 0 or 1?

The Y intercept of a straight line is simply where the line crosses the Y axis. In the above diagram the line crosses the Y axis at 1. The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..
