1. X/Y = Z

if x = 6, y = 2, then z = 3, not even

if x = 6, y = 3, then z = 2, even

2. Z=XY 

so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)

Sufficient, as if square of an integer is even ,then the integer is even

Which equation represents a line that passes through (-2,4) and has a slope of 2/5?

oksano4ka [1.4K]

Answer:

$\large\boxed{y=\dfrac{2}{5}x+\dfrac{24}{5}}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the slope $m=\dfrac{2}{5}$ and the point (-2, 4).

Put them in the equation of a line:

$4=\dfrac{2}{5}(-2)+b$

$4=-\dfrac{4}{5}+b$ add 4/5 to both sides

$4\dfrac{4}{5}=b\to b=\dfrac{24}{5}$
