# finding slope of a line given its graph

Finding the slope of a line gives us a numerical measure of the steepness or inclination of that line. y Q(x2, y2) P(x1, y1) (x2, y1) NOTE Recall that an equationIts graph is always a straight line. NOTE x1 is read x sub 1, x2 is read x sub 2, and so on. The 1 in x1 and the 2 in x2 are called subscripts. 3. Graph a line whose equation is in the form Ax By C. 4. Find the equation of a line given its slope and yintercept. The slope of a line is rise over run. Learn how to calculate the slope of the line in a graph by finding the change in y and the change in x. Finding the slope, given two points. The steepness of a line is called its slope. Here are the graphs of two equations. Slope Less 5-1 Slope Math Vocabulary Slope: The diagonal slope of a line on a graph that runs through given points Graphing Slope When graphing slope we need toFinding the Slope of a line from its graph. Find the Slope Using the Rise/Run Triangle Using two points. The slope of a line (m) is a ratio that compares the vertical change to the corresponding horizontal change as we. move along the line from one point to another.Example 2: (Finding the slope of a line given two points). Be able to find the slope of a line from its graph.Find the slope of the line that passes through the 2 pts: (1, 2) and (4, -5).

Given any 2 pts Ex 1: Find the Equation of a Line in Slope Intercept Form Given the Graph of a Line.Quickly master how to find the slope of a line from its graph using the slope equation. Watch more lessons like this and try our practice at (If youre not sure that the two formulas above give exactly the same values, no matter what pair of points is plugged into them, then pick someIn the previous example, we started with a graphed line and its equation, found a couple points on the line, found the slope and the y-intercept, and noticed Use slope to graph linear equations in two variables. Find the slope of a line given two points on the line.Given an equation of a line, you can find its slope by writing the equation in slope-intercept form.
