How to find y intercept with 2 points.

How the equation of a line relates to the graph of its y-intercept. The Y-Intercept of a line is the point where a line 's graph intersects (crosses) the Y-axis. 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). To find x intercepts, find x to make y=). That is: solve x^2+2x-3 = 0 (x-1)(x+3) = 0 The x intercepts are -3 and 1. Find y intercepts by finding y when x=0. y = (0)^2 +2(0) -3 = -3 The y intercept is -3. Find the vertex: The vertex of y = ax^2 +bx +c has x coordinate -b/(2a) So the graph of y=x^2+2x-3 has vertex at x= -(2)/(2(1)) = -1 The axis …The y-intercept is at the coordinate that has a 0 for the x-coordinate. X is 0 here and y is -3. X is 0 and y is -3. This was actually one of the points, or one of the pairs that we first tried out. You can validate that 6, 0 satisfies this equation right over here. If x is 6, 1/2 x 6 is 3, -3 is indeed equal to 0. In an equation in slope-intercept form (y=mx+b) the slope is m and the y-intercept is b. We can also rewrite certain equations to look more like slope-intercept form. For example, …To find where y=1/2x+5 and the original line y=-2x intersect, set them equal to each other. Let y in both of the equations equal the same value. You are doing this because at the two lines' point of intersection, both lines will share the same x and y value. So, let y=1/2x+5 equal y=-2x. That means. -2x = 1/2x+5.

Given two points on a graph with coordinates of X1,Y1 and X2,Y2, the slope of a straight line through the two points can be calculated as m=(Y1-Y2)/(X1-X2) The equation for the line can then be written as Y=mX+k, where k is some constant number. Note that m will be positive for lines that slant up from left to right, and negative for lines …To find the x-intercept we generally just use the same formula 'y=mx+b'. The reason that 'b' is the y-intercept is because at the 'y-axis, x=0'. By this I mean if you look at any graph, for the point a line touches the y-axis, the x-value of a coordinate is always = 0. Knowing this, if you substitute 0 in for x in the formula you get:

The y-intercept above is the point (0, 2). Notice that the y -intercept always occurs where \(y=0\). To find the x – and y -intercepts of a linear equation, you can substitute 0 for y and for x respectively.

A vertical intercept is a point where a line crosses the vertical axis, or y-axis, on the Cartesian coordinate plane. When evaluating a function, the vertical intercept can be foun...What About y = mx + b ? You may already be familiar with the y=mx+b form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis. So point (x 1, y 1) is actually (0, b) and the equation becomes: Courses on Khan Academy are always 100% free.

When Y is isolated already and the equation is in vertex form, it is easier to pick values of X and calculate Y especially when you have a 2nd degree (quadratic) equation or higher degree.

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.. There are basically two intercepts, x-intercept and y-intercept.
