:) Hi all! My friend recommended this site for me! Hope you can help me out!
I have a few quesions:
1.Find the angle of the line joining the points (-1,2) and (4,6), makes with the x axis.
2.Find the equation of the line passing through (-1,2) and making an angle of 53 degrees and 8 minutes with the x-axis.
3.Find the equation of the line containing the point (2,-5) that is
a) parallel to the line y=-2x+7
b) Perpendicular to the line y = -2x +7
4. Find the values of a and b for which x^3 + ax^2 - 10x + b is divisible by x^2 + x - 12.
THanks a lot for your help!
