Linear Equations Chapter 2/unit 1 10-09-2017

Objective: Student’s will be able to write liner equations in two variables using slope-intercept form to represent the relationship between two quantities.

Slope-intercept form Y = mx + b m- represents the slope of the line X -the x-coordinate of ordered pairs (x,y) B -the y-intercept of the graph; the line intersects the y-axis at the point (0, b).

Essential Understanding The slope-intercept form of a linear equation is used when you know the slope and the y-intercept of the line.

Essential Question What information does the slope-intercept form of a linear equation reveal about a line? The slope of the line and the y-intercept are given by the slope-intercept form, so the line is easily graphed.

Essential Question What is the relationship between the b-value of the equation and the graph? The b-value of the equation represents the y-intercept of the graph. The line intersects the y-axis at (0,b).
