Q. Al ChatDeltaMath Student A9Detamath Student A.A scale drawing of atxt2speech [ A alegbratorJupiterclassroomAll BookmarksFind the equation that represents the proportional relationship in this graph, for y in terms of x.
Determine Constant of Proportionality: To find the equation of a proportional relationship, we need to determine the constant of proportionality, which is the slope of the line in the graph.
Pick Two Points: Pick two points on the line in the graph. Let's say the points are (x1,y1) and (x2,y2).
Calculate Slope: Calculate the slope k using the formula k=x2−x1y2−y1. Suppose we picked points (2,4) and (4,8).
Plug in Values: Plug in the values into the slope formula: k=4−28−4=24=2.
Equation of Proportional Relationship: The equation of a proportional relationship is y=kx. Since we found k=2, the equation is y=2x.
