my friend is studying to pass the GRE:
A line in the xy-coordinate place has x-intercept A and y-intercept b, where a and b are nonezero. The slope of this line is
?1/ab ?−b/a ?−a/b ?b/a ?a/b
the answer is 2
but can you explain how to get the answer?
do you know anyone that can explain how to get to the answer?
