A line has a slope of - 7 and includes the points (1, g) and (0, -2). What is the value of g?

-9

If you use this equation:

y2-y1
———
x2-x1

Input it into the equation:

-2-g -2-g
——- = ——
0-1 -1

g would need to be -9:

-2+9 7
——- = ——- = -7 (which is the slope)
-1 -1

1. If it is intersection then it SHOULD be included in both the sets right? Now we know that odd numbers from 1-100 but the second set are multiples of 5 from 50-150! So we mainly need to look for common numbers which are ODD and are a MULTIPLE OF 5 BETWEEN 50 - 100!! So A={51,53,57,59,6199} B={55,60,65,7095} [We stop till 100 because set A has no such element] So what is A ∩ B here? A ∩ B = {All odd numbers and multiples of 5 between 50 - 100}
