How do you determine slope and y intercept?
Steps for graphing an equation using the slope and y-intercept:
- Find the y-intercept = b of the equation y = mx + b.
- Plot the y-intercept. The point will be (0, b).
- Find the slope=m of the equation y = mx + b.
- Make a single step, using the rise and run from the slope.
- Connect those two points with your line.

For.
How do you find the y-intercept with?
Since the y-intercept always has a corresponding x-value of 0, replace x with 0 in the equation and solve for y. On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.
How do you find the value of y in a slope?
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.
What is Y in slope intercept?
Purplemath. 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).
How do you find the y-intercept from two points?
Use the slope and one of the points to solve for the y-intercept (b). One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b.
What is y2 y1 x2 x1?
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
What is the y-intercept of y =- 3?
Algebra Examples Using the slope-intercept form, the y-intercept is −3 .
What is the y-intercept of y =- 2x?
Using the slope-intercept form, the y-intercept is 0 .
What is the y-intercept for kids?
the point on the y axis where it is crossed by a graph. at the same point x = 0.
What is point slope form?
The point slope form is also a type of slope intercept form where the distance between the two points is estimated by drawing a straight line between them. Basically, this form is taken from the theory of finding the slope or steepness of a line when two points are given.
What is the graph of a linear equation?
The graph of the linear equation y = mx + c is a line with m as slope, m and c as y-intercept. This form of the linear equation is called slope-intercept form. The values of m and c are real numbers.
Community Q&A
If I have (3, -12) as my points and an x-intercept of one, what would the y-intercept be?
Tips
For more complicated equations, try to isolate the terms containing y onto one side of the equation.
