Given <1 and <2 are a linear pair, find the value of x if m<1 = 2x-5 and m<2 = 4x-7 This is geometry, and I need help because I don't know if it adds up to 90 or 180 degrees.

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
