Respuesta :

Y= mx + c
1 = 4 * 8 + c
1 = 32 + c
1 - 32 = c
-31 = c

Therefore the y intercept is -31

Equation of line: y = 4x - 31

Answer: The y intercept is -31

Step-by-step explanation:

y = mx + b

y = 1

1 = mx + b

m = 4

1 = 4 · 8 + b

1 = 32 + b

1 - 32 = b

-31 = b

y - mx + b

y = 4x -31
