Question :

A student is attempting to find the equation of a line given a point and the slope. Which of the following statements best applies to the sample mathematical work shown below? Given (10, 2) with a slope of 1, I find an equation for the line by plugging in values I'm given into a point-slope form equation. Thus I have y (2) = 1( x 10), which results in an equation of y = x + 8. A. The student improperly set up the equation to find the y-intercept. B. The student used the correct equation to find the y-intercept. However, he did not solve for the y-intercept properly. C. The slope in the final equation is not correct. D. The mathematical work shown above is correct.
