Unformatted text preview: A ( 3, - 1 ) and perpendicular to the line 2 x- 3 y = 2. (Solution) The given line is Since the slope of this line is , the slope of the desired line is (take inverse and multiply it by -1). Use a point-slope form of a line equation to get 10. Find the slope-intercept form of the line with the x-intercept 11 and y-intercept - 4. 11-4 (Solution) The slope is . Definitely, the y-intercept is . Hence the slope-intercept form is . 11. Find the slope-intercept form of the line through the points A (2, 3) and B ( - 1, 4). (Solution) The slope is . Note that we are asked to find the slope-intercept form. Hence we apply a point-slope form to get...
