20 ! 1. which linear equation has a slope of 3 and a y-intercept of –2? y = 3x + 2 y = 3x – 2 y = –2x + 3 y = –2x – 3 2.adriana writes the equation y = 2x + 4 to represent a line on a graph. henry writes an equation that has a y-intercept that is 1 unit lower on the graph but has the same slope as adriana’s line. which is henry’s equation? y = x + 4 y = 3x + 4 y = 2x + 3 y = 2x + 5

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
