Astudent 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.
