1. Sketch y =2x + x indicating intercepts. 2. Find the intersection points of x +y=4 2x+y=1 3 . Find the slope of the line trough (7/8,3/4),(5/4,1/4) 4. Find the slope and y intercept of 6x - 5y = 15. 5. Write the equation of the line which is (a) parallel to, and (b) perpendicular to the line 3x + 4y = 7 and passes through the point (-6, 4) 6. Find the domain of f(x)=x+(4x). [the range is tricky]
