What is the slope of the line with x-intercept?
We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.
How do you find the slope of a line with the y-intercept?
The equation for slope-intercept form is: y=mx+b In this form, m is the slope of the line and the b is the y-intercept.
What is the slope and y-intercept of x =- 2?
x=2 is a line parallel to y axis and hence y-intercept is 0 as it never cuts the y axis.
How do you find y if you know slope and X?
Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 – y2] / [x1 – x2]. If you know x, you can solve for y to find the y value for the slope of the line.
How do you find the X and y-intercept?
Finding x-intercepts and y-intercepts
- 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.
- To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
- To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
Is X intercept the same as slope?
If we’re talking about a graph in the standard x-y plane . . . Slope (aka rise over run, gradient) measures how fast y changes with respect to x. An x-intercept is a point where the graph touches the x axis. A y-intercept is a point where the graph touches the y axis.
How do you find y intercept?
The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. 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.
How do you find the Y intercept with two points and slope?
Steps
- Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11)
- Substitute the slope(m) in the slope-intercept form of the equation.
- Substitute either point into the equation. You can use either (3,5) or(6,11).
- Solve for b, which is the y-intercept of the line.
- Substitute b, into the equation.
What is the x-intercept in X 2?
The x-intercept is −2 .
What is the X-intercept of Y 2?
There is no x – intercept, because: the line is horizontal. on the x -axis, y=0 , this is not possible because y=−2.
