How do you solve for
Y=-9x-4
Y=5x+10
?

{y,x} = {-1,1}

Step-by-step explanation:

Solve equation for the variable  y

     y = -5x + 4

this in for variable  y  in equation

   (-5x+4) - 9x = -10

      - 14x = -14

Solve equation or the variable  x

      14x = 14

  x = 1

By now we know this much :

   y = -5x+4

   x = 1

Use the  x  value to solve for  y

   y = -5(1)+4 = -1

40 x 50 = 2000

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
