equation for the perpendicular bisector of the line segment whose endpoints e(-1,5) and (-7,-7). Find an are

Find the equation of the line passing through the points: (5,21) and (-5,-29).

Find the form of the equation y1 which is a straight line through points A (5,8) and B (- 1, - 4) that intersect with the line y2 = - 2 x + 6. Draw the two lines and mathematically determine the point of intersection, which corresponds to the picture you made.

(8,-9); 8x+7y=4write the equation in slope-intercept form.
