In the xy-plane, the points with coordinates (0,-5) and (6,-2) lie on line L. Line P contains the point with coordinates (-5,0) and is perpendicular to line L. What is the x-coordinate of the point where lines L and P intersect?
Find the equation of the line formed by the joining of the points (0,-5) and (6,-2).

Yes, I think I need to find the equation of both lines.
But the teacher said that I need to points
When you find the equation of line L, find a slope perpendicular to it and use this slope along with the point (-5,0) to find the equation of line P.
And I have only one point and an unknow point for the second line.
Then set the equations equal to each other, solve for x, plug this x into any of the two equations, get y and you have your point of intersection (x,y).
I'll show my word.
Work.
