Help me solve this please

-1/2

Step-by-step explanation:

2(5y + 3) + 4y = -1

2*5y + 2*3 + 4y = -1

  10y + 6 + 4y  = - 1       {Combine like terms}

   14y + 6 = -1                {Subtract 6 form both sides}

       14y = -1 - 6

       14y = -7             {Divide both sides by 7}

         y = -7/14

y = -1/2

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
