RETAKE UNDERSTAND PROPORTIONAL RELATIONSHIPS AND SLOPE

The chart of a proportional relationship is given and an equation of a proportional relationship y = 15x. If I graph both, would the line using the points of the chart be steeper or less steep than the line of the equation?

• The line using the points of the chart be less steep than the line of the equation.

• The line using the points of the chart be steeper than the line of the equation.

• Both have the same slope.

Which graph is proportional?

• A
• B
• C and D
• All of the graphs are proportional

Gabriel plots the points (-1, -2), (7, 2), and (-6, -9) on a coordinate plane. explain to him without graphing why the points do not lie along the same graph.

• The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) is not the same as the slope from (-6,-9) to (7, -2).

• The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) is the same as the slope from (-6,-9) to (-1, -2).

• The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) and the slope of (-6,-9) to (-1, -2) are undefined.

• The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) and the slope of (-6,-9) to (-1, -2) are 0.
