Question

What is the slope of the line that passes through the given points?

(1/2, 3) and (2, 3/4)

A. -3/2
B. -2/3
C. 2/3
D. 3/2

When I tried to solved this I got 2.25/-1.5

Answer 1

Slope = (y2 - y1)/(x2 - x1)

= (3/4 - 3) / (2 - 1/2)

= (3/4 - 12/4) / (8/4 - 2/4)

= (-9/4) / (6/4)

= (-9/4) × (4/6)

= -9/6

= - 3/2

Answer

A. -3/2

Answer 2

The answer is A.

We have to find the difference between the cooridants.

1/2-2= -1 1/2 = -3/2

3-3/4 = 2 1/4 = 9/4

We then divide 9/4 by -3/2 (9/4 times -2/3) and we get -18/12 if we divide the top and bottom by 6, we get -3/2.
