What is the equation if there is no y-intercept?

If a line has no y intercept, then it can only be parallel to the y axis and therefore has an equation of the form x=a for some constant a .

Is slope-intercept the same as y-intercept?

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”.

Can a function have no y-intercept?

In fact, any time a function is undefined at 0, it will have no y-intercept.

How do I find slope and y-intercept?

Summary. The slope-intercept form of a line is: y=mx+b where m is the slope and b is the y-intercept. The y-intercept is always where the line intersects the y-axis, and will always appear as (0,b) in coordinate form.

How do you find y intercept from slope?

The slope intercept form equation is expressed as y = mx + c, where ‘m’ represents the slope of the line and ‘c’ represents the y-intercept of a line. You can find the equation of a straight line based on the slope and y-intercept using this slope intercept form calculator.

What is the point and slope of the equation y?

The “point-slope” form of the equation of a straight line is: y − y 1 = m (x − x 1) The equation is useful when we know: one point on the line: (x1,y1)

What is the formula for y – intercept?

Y-intercept is a characteristic of linear equation plots that are always straight lines. Linear equations are given in the form: y = axe + b.

How do you find the slope of a given equation?

Formula/Equation of Slope. The formula to find the Slope when radius is given is Slope = (y2-y1)/(x2-x1) where x1,y1 and x2,y2 are the two given points.
