What is the slope when there is no X?

What is the slope when there is no X?

If an equation of a line in slope-intercept form (y=mx+b) has no x variable, this means that the slope is 0.

What if there is no x intercept in a line?

If a line never passes through the x axis, therefore having no x intercept, it must be parallel to the x axis, or a horizontal line. It is also true that this line is perpendicular to the y axis.

Is it possible for a line to have no y-intercept and NO x intercept?

A line can have no x-intercept or no y-intercept, but not both. The x-intercept is where a line crosses the x-axis. For example, a horizontal line such as y=−3 has a y-intercept of (0,−3) , but there is no x-intercept because the line does not cross the x-axis.

What is a line with no slope called?

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).

What graph has no x-intercept?

Students are often surprised when they graph a parabola a notice that the parabola has no x intercepts. But as the graph above shows, parabolas do exist that do not cross the x axis.

How do you tell if a graph has no x intercepts?

So, if we can’t solve for x, that means there are no x-intercepts. Let’s graph the parabola using the y-intercept (0, 5) and the vertex (3/2, 11/4). Remember, the parabola should not cross the x-axis anywhere.

What is the y-intercept if the slope is 0?

1
Slope = 0 y intercept =1.

How do you find y intercept using slope?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

What is the formula for finding the slope of a line?

Slope Formula. The slope of a straight line is commonly represented using the equation y = mx + b where m is the slope of the line.

How do you determine the slope of a line?

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. Teachers use different words for the y-coordinates and the the x-coordinates.

What is the formula for finding y intercept?

The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b.
