a. The constant of proportionality is Response area
b. Write an equation that represents the linear graph. Response area
c. This is a proportional relationship because the graph shows
a. The constant of proportionality is the slope of the line, which is equal to 2. Response area: 2.
b. Write an equation that represents the linear graph. The equation is y = 2x, where y represents the dependent variable and x represents the independent variable. Response area: y = 2x.
c. This is a proportional relationship because the graph shows a straight line passing through the origin, indicating that the dependent variable (y) is directly proportional to the independent variable (x). Response area: a straight line passing through the origin.
NO
I apologize for the incorrect response. Let me try again.
a. The constant of proportionality is the slope of the line, which can be calculated as the change in y divided by the change in x. Looking at the graph, we can see that the change in y for every change in x is 2. Therefore, the constant of proportionality is 2. Response area: 2.
b. To write an equation that represents the linear graph, we can use the slope-intercept form of a linear equation, which is y = mx + b. We know that the slope (m) is 2, and we can find the y-intercept (b) by looking at the point where the line crosses the y-axis, which is (0, 3). So the equation representing the linear graph is y = 2x + 3. Response area: y = 2x + 3.
c. This is a proportional relationship because the graph is a straight line passing through the origin, which indicates that the dependent variable (y) is directly proportional to the independent variable (x). In other words, as x increases, y increases in a constant ratio of 2:1. Response area: a straight line passing through the origin.

Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse. a. Triangles ABC and DEF are called Response area triangles. b. The slope of the line AG can be written as Response area c. This is a Response area relationship. Question 2 19. Upload Files Here *3Vs/5Ps for each Connexus lesson in Unit 3 - can be found on the
a. The constant of proportionality is the slope of the graph. To determine the slope, we can choose two points on the graph and calculate the change in y-coordinate divided by the change in x-coordinate. The slope represents the ratio between the change in y-values and the corresponding change in x-values.
b. To write an equation that represents the linear graph, we need to determine the slope and the y-intercept. The slope can be found using the constant of proportionality from part a, and the y-intercept is the point where the line intersects the y-axis. Once we have those values, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.
c. A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0). In a proportional relationship, the two variables have a constant ratio, meaning that their values increase or decrease in a consistent manner.
