Viktor [21]

Answer:

$y+6=2x$

Step-by-step explanation:

we have

x-intercept (3,0) and y-intercept (0,-6)

step 1

Find the slope

The slope is

$m=(-6-0)/(0-3)=2$

step 2

Find the equation of the line into point slope form

The equation is equal to

$y-y1=m(x-x1)$

we have

$m=2$

$(0,-6)$

substitute

$y+6=2(x-0)$

$y+6=2x$ ----> equation of the line into point slope form

Andru [333]

Answer:

$\huge\boxed{x>-2\to x\in(-2;\ \infty)}$

Step-by-step explanation:

$y=\log(x+2)\\\\\bold{Domain:}\\\\x+2>0\qquad|\text{subtract 2 from both sides}\\\\x+2-2>0-2\\\\x>-2$
