Aline goes through the points (8,9) and (-2,4). a) what is the slope of he line? show your work b) write the equation of the line in point- slope form. show your work. c) write the equation of the line in slope-intercept form. show your work. a, b,c are all parts of the question that have to be answered.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
