In this lesson, we learned how to find the slope between two points given their x- and y-coordinates. We also learned how to use the slope to graph a line that passes through the two points, as well as how to calculate the y-intercept of the line. With these skills, we can easily...
Given two points, (x1,y1)(x1,y1) and (x2,y2)(x2,y2), the following formula determines the slope of a line containing these points: m=y2−y1x2−x1m=y2−y1x2−x1 Example 7: Finding the Slope of a Line Given Two Points Find the slope of a line that passes through the...
vertical line x=ax=a; all the xx -coordinates are the same.So how do we find the slope of the horizontal line y=4?y=4? One approach would be to graph the horizontal line, find two points on it, and count the rise and the run. Let’s see what happens. We’ll u...

Given only two points on a Cartesian coordinate system, the x- and y-intercepts of a linear function can be found by examining the graph. In the illustration below, given a line defined by coordinates (-4, 4) and (4, 0), the y-intercept is (0, 2), and the x-intercept is (4,...
This game is designed to help students practice finding Linear Equations in Slope-intercept form. Students will find the Linear Equation given a graph, given the slope and y-intercept, given the slope and a point, and given two points. ...
Lastly, the point slope formula is the easiest formula to get to if the slope and a point on the line is given. The equations to find the slope are outlined here: The three equations for finding the slope of a line. Standard Form Slope The standard form slope formula for two variables...
On these printable worksheets, students are given ordered pairs or a graph and are instructed to find the slope.
Linear equation in two variables: is an equation that can be written as + = where and are real numbers and and cannot both be zero. Important Formulas: Slope formula: The slope of the line through the points (11) and (22) is given by = 1 2 1 2 = 2 1 2 1 = change in change...
Also called spirit level. b. Such a device combined with a telescope and used in surveying. c. A computation of the difference in elevation between two points by using such a device. adj. 1. Having a flat, smooth surface: a level countertop. 2. Being on a horizontal plane: a level ...
