a. Imagine the triangle described by the points (−3,6),(x,6), and (x, y) where x > − 3 and y > 6. Write an expression for the length of the horizontal leg in terms of x?

Aline passes through the points (5,4) and (2.1). part a.) what is the slope of the line that passes through these points? show work. part b.) what is the equation of the line that passes through these points. show work. part c.) where does the line intercept on the x& y axis? show work

Me because i don't understand how to do it.: )
