Question

what is the y intercept of -10x -1/2 y = 5 ?

Answer 1

y-intercept is when x = 0  or the b-value when in the form y = mx + b

-10x - $\frac{1}{2}y$ = 5

-10(0) - $\frac{1}{2}y$ = 5

      $\frac{-1}{2}y$ = 5

$-2(\frac{-1}{2}y)$ = -2(5)

 y = -10

Answer: (0, -10)

-10x - $\frac{1}{2}y$ = 5

+10x        +10x  

$\frac{-1}{2}y$ = 10x + 5

$-2(\frac{-1}{2}y)$ = -2(10x + 5)

y = -20x - 10

              b = -10

Answer 2

The y intercept is -10.
