Write each equation in slope intercept form. identify the rate of change and the y intercept ( write in coordinate form). show make sure to include the

ABOUT SLOPE INTERCEPT FORM:

You have to isolate y in order for the equation to be in Slope Intercept Form...

9:

7x + 10y = 7x + 50

-7x            -7x

10y = x + 50

10        10

y = 10x + 5 where 10 is the slope AKA the ROC & 5 is the y - intercept AKA the starting point.

10:

9y = 4x + 27

9            9

y = 4/9x + 3 where 4/9x is the slope AKA the ROC & 3 is the y- intercept AKA the starting point.

11:

3x = 42

3        3

x = 14

Um.. For this one, IDK... Where is the the other variable(y)?

12:

6x - 42y = 168

-6x              -6x

-42y = -6x + 168

-42            -42

y = -6/42x + 4 where -6/42x is the slope AKA the starting point & where 4 is the y - intercept AKA the starting point.

I think I might've did the last 2 wrong... I'm not sure... Really really sorry if I'm incorrect...

1. 34

2. 268

3. x=14.4

is only a line? i think so
