2.)

0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9

\frac{ - 3y}{ - 3}  =  \frac{6x + 9}{ - 3}  \\  \\ y =  - 2x - 3
By isolating y we now have the equation in slope intercept form:
y = mx + b

Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.

4.)

Similarly, #4 is already in slope intercept form so we can solve it by inspection. So for #4 the slope is -1 and the y - intercept is 2.

stiv31 [10]
The answer to this, your question is                                                                               h = -16t • 2 + 48t + 6
h = -32t + 48t + 6
h = 16t + 6     HOPE I HELPED IN A WAY!                                                                                                                                             ~Marcey<3
