ABOUT SLOPE INTERCEPT FORM:
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
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...
