Final answer:Given thecurrentinformation, the known line has a slope of 3 as there is a vertical rise of 3 for each horizontal increase of 1. However, we do not have enough information to determine the slopes of lines k and j.Explanation:From your question, it seems you want to know the slope of lines k and j. However, based on the information given, we only have details for a line whichintersectsthey-axisat point 9 and has aslopeof 3. To find the slope of a line, we use the formula rise/run. That is, the change in the vertical axis (rise) divided by the change on the horizontal axis (run). In the given information, there's a rise of 3 on the vertical axis for every increase of 1 on the horizontal axis which is mentioned as the slope of the line. Unfortunately, we do not have enough information to determine the slopes of lines k and j specifically. Without additional data - such as coordinates for two points on each line - it is impossible to give a definite answer for the slope of these lines.Learn more about Slope here:brainly.com/question/19131126#SPJ11...
