What is the Y intercept of the equation

When the equation of a line is written in slope-intercept form (y=mx+b), the y-intercept is the constant, which is represented by the variable b. For example, in the linear equation y=4x−5, the y-intercept is −5.

How do you find the y-intercept in an equation?

Using the “slope-intercept” form of the line’s equation (y = mx + b), you solve for b (which is the y-intercept you’re looking for). Substitute the known slope for m, and substitute the known point’s coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.

What is y-intercept of 3?

A y-intercept of 3 means that a line’s graph intersects the Y-axis at the point (0, 3). A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0, -4).

What is y-intercept in maths?

y-intercepts are when the line touches the y-axis. To find these, find the y when x = 0. The point for a y-intercept will look like (0,y) x-intercepts are when the line touches the x-axis. To find these, find the x when y = 0.
