Pre-assessment on graphical mathematics skills among physical science students
A pre-assessment in mathematics skills was administered to 23 students in SC 130 Physical Science on the first day of class. The pre-assessment differed from prior terms. This term the first question more no longer used a density of soap example. Instead the graph and questions referred to an algebraic xy labelled scatter graph. Question two was also simplified with the answers to 2e and 2d being able to be read from the table directly rather than calculated from the equation of the line. This term the slope formula and point-slope form were not provided. 1. Answer the following questions based on graph one. a. __________ What is the slope of the line? b. ______________ What is the y-intercept of the line? c. y = _________ x + __________ Write the y = mx + b slope-intercept equation for the line. 2. A student rolled a ball along the sidewalk measuring the time and distance that the ball rolled. The data is recorded in the table below. a. Plot the...
