1.

 

equation of line that passes through  (2, -3)  with a slope of  \(\frac12\)  is

 

y + 3  =  \(\frac12\)(x - 2)

 

y + 3  =  \(\frac12\)x - 1

 

y  =  \(\frac12\)x - 4

 

The y-intercept is the point where  x = 0 . When  x = 0 ,

 

y  =  \(\frac12\)(0) - 4  =  -4

 

When  x  is  0 ,  y  is  4 .  So the y-coordinate of the y-intercept is  4 .

It says the answer is incorrect, do you know where you went wrong?

Hectictar's answer is correct

 

She just made a typo....the y intercept  is  -4

 

cool cool cool
