The greatest common factor of 60w5y3 and 78 wy2 is
6 wy2
6 w5y3
13 w5y3
2 wy2

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Can someone tell me if this is perpendicular? !

What are the excluded values? m+5/mn+3m
