Find the value of x so that the line that passes through (x, 5) and (12, 2) is perpendicular to the line that passes through (0, 1) and (2, 7). find x

find the value of x so that the line that passes through (x, 6) and (10, -3) is parallel to the line that passes through (7, 2) and (6, 11). find x

a line segment has endpoints at a(-2, 4) and b(-4, 2). writ4e an equation in slope-intercept form for a line that bisects this segments that is parallel to the line y = -2x + 5.
