Direct Variation - ChiliMath
www.chilimath.com › direct-variationTo write the equation of direct variation, we replace the letter k by the number 2 in the equation y = kx. When an equation that represents direct variation is graphed in the Cartesian Plane, it is always a straight line passing through the origin. Think of it as the Slope-Intercept Form of a line written as y = mx + b where b = 0
DIRECT VARIATION TABLES AND SLOPE
www.oregonfocus.com › inside › mediaW hen a graph on a coordinate plane is a straight line that goes through the origin it is called a direct variation graph. In this lesson you will investigate direct variation tables and graphs in Quadrant I. As the x-coordinate gets larger, the y-coordinate also gets larger at a constant rate. For example, Stein walks 4 miles per hour in a race.
