Answer:

See Below.

Explanation:

Given :-

Line A equation

Line B graph

To Find :-

Value of the y-intercept of line A and line B

Solving :-

  1. Line A

=> y + 2 = -(x + 1)

=> y + 2 = -x - 1

=> y = -x - 3

=> y-intercept is (0, -3)

2. Line B

=> y = x/4 - 1

=> y-intercept is (0, -1)

The y-intercept is where the x-value is zero.

  • Equation A


y+2=-(x+1)\\y + 2 = -(0+1)\\y = -1-2 = -3

Y-intercept of Equation A is (0,3)

  • Equation B

The value of y where x is 0 is -1.

The Y-intercept of line B is (0,-1)

Hope that helps!
