What is the reciprocal of the number 2/7 ?

1 answer:

6 0

Reciprocal just means flipping a fraction by swapping the place of the numerator and denominator.
Switching 2 and 7 would change it to 7 over 2.
Simplifying 7/2 would result in 3 and 1/2.
So the answer is D. 3 1/2.

Answer:

y = 1/2x - 3

Step-by-step explanation:

the slope:

$m=\frac{-4-(-1)}{-2-4} =\frac{-4+1}{-6} =\frac{-3}{-6} =\frac{3}{6} =\frac{1}{2}$

the equation:

with the point (4, -1)

$y-(-1)=\frac{1}{2} (x-4)$

$y+1=\frac{1}{2}x-2$

$y=\frac{1}{2} x-2-1$

$y=\frac{1}{2} x-3$
