E.10 Checkpoint: Parallel and perpendicular lines
The equation for line g is x + 4y = 12. Line h is perpendicular to line g and passes through
the point (-3, -5). What is the y-intercept of line h?

Respuesta :

Answer:

7

Step-by-step explanation:

x + 4y = 12

4y = -x + 12

Line G:

y = -1/4x + 3

Line H:

y = 4x + b

-5 = 4(-3) + b

-5 = -12 + b

7 = b
