What is y-intercept??? Is it like slope?????
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".
Thx :)
your welcome :3
the y-intercept is where the graph of a function touches the y-axis.
for example, in a linear equation, the y-intercept is *b* in the equation y=ax+b
The y-intercept is a concept in mathematics that is used to describe the point where a straight line crosses the y-axis on a coordinate plane. It is labeled as the value of y when x is equal to 0. The y-intercept is different from the slope, which measures the steepness of a line. The slope describes how the y-coordinate changes for a given change in the x-coordinate.
To find the y-intercept of a line, you can follow these steps:
1. Identify the equation of the line, which is usually written in the form 'y = mx + b', where 'm' represents the slope and 'b' represents the y-intercept.
2. Look for the value of 'b' in the equation. This value represents the y-intercept.
3. If the equation is not already in the 'y = mx + b' form, rearrange the equation to isolate the 'y' term.
4. Once you have identified the value of 'b', you can consider it as the y-coordinate of the point where the line crosses the y-axis.
For example, in the equation 'y = 2x + 3', the value of 'b' is 3, so the y-intercept is the point (0, 3) on the coordinate plane.
