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 (1,-2) with a slope of 2/3, I find the equation of the line by plugging the values I'm given into the slope intercept form of the equation. Thus I have l=2/3x(-2)+b which results in b=7/3. Thus, the equation of the line is y=2/3x+7/3.
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 solution is not correct.
D. The mathematical work is correct.
