a. The graph has a positive slope. It is a proportional graph as the points lie on a straight line. The y-intercept is 2.
b. The slope of the graph means that for every 1 unit increase in the x-coordinate, the y-coordinate increases by 3 units.
c. The y-intercept of the graph means that when the x-coordinate is 0, the y-coordinate is 2. This is the starting value of the dependent variable.
d. The graph of the line shows a direct relationship between the x and y variables, where the y-values increase proportionally with the x-values.

a. Using the graph, describe the key characteristics of the graph (positive/negative slope, proportional/non proportional, y-intercept).
b. Write in words what the slope of the graph means in context.
c. Write in words what the y-intercept of the graph means in context.
d. Write in words what the graph of the line is showing.
