How do you find the y-intercept when given two points.

You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6; This is slope intercept form, y = 3x - 6. Slope is the coefficient of x so in this case slope = 3; How to Find the y-Intercept. The y-intercept of a line is the value of y when x=0. It is the point where the line crosses the y axis.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).Elizabeth P. Sep 22, 2014. If given a graph: the y-intercept passes through y-axis. Example: If a graph passes the y-axis at -1, then the y-intercept is -1. If you can not … 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. Oct 6, 2021 ... Since two points determine any line, we can graph lines using the x- and y-intercepts. · To find the x-intercept, set y=0 and solve for x. · To ....

Now given that, what I want to do in this exercise is look at these graphs and then use the …We want to graph a line parallel to this line and passing through the point \ ( (−2,1)\). We know that parallel lines have the same slope. So the second line will have the same slope as \ (y=2x−3\). That slope is \ (m_∥=2\). We’ll use the notation m∥m∥ to represent the slope of a line parallel to a line with slope m.

This is called the sum of squared errors (SSE). Using calculus, you can determine the values of a and b that make the SSE a minimum. When you make the SSE a minimum, you have determined the points that are on the line of best fit. It turns out that the line of best fit has the equation. ŷ = a + bx ŷ = a + b x. where.

The method for finding the \(y\)-intercept of a quadratic function or the \(y\)-intercept of a parabola is the same as that of a line. If a quadratic equation is given, substitute \(x = 0\) and solve for \(y\) to get the \(y\) intercept. Finding the \(y\)-Intercept – Example 1: Find the \(y\)-intercept of the equation \(y=x^2-2x-3\). Solution:Equation of a straight line. The general equation of a straight line is: \ (y = mx + c\) where m is the. gradient. and c is the. y-intercept. (where the straight line cuts the y-axis)b = the y-intercept at the point (0, b) So, in your equation, your y-intercept = (0, -3). Start by graphing that point. Then use the slope to find more points. Your slope = 1/2. This means from the point (0, -3), go up 1 unit and right 2 units to find the next point. You can repeat this as many times as you want to find points on the line.AboutTranscript.

Feb 6, 2024 · Add 2y to both sides to get 6x = 12 + 2y. Subtract 12 from both sides of the equation to get 6x - 12 = 2y. You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6. This is slope intercept form, y = 3x - 6. Slope is the coefficient of x so in this case slope = 3.
