Answer:
The last one 5x-3y=15 This is the same as y= (5/3)x -5
Step-by-step explanation:
5x-3y=15
Move 5x to the right (becoming negative)
-3y = -5x +15
Divide everything by - 3
y= (5/3)x -5
y intersect= -5 ( line crosses y coordinate at -5)
Slope = 5/3 From -5 you start counting (5 up,3 right,5 up,3 right.... OR 5 down,3 left,5 down,3 left........)
To solve the equation, you need to isolate/get the variable "P" by itself in the equation:
P - 3 = -4 Add 3 on both sides to get "P" by itself
P - 3 + 3 = -4 + 3
P = -1
PROOF
P - 3 = -4 Plug in -1 for P
-1 - 3 = -4
-4 = -4
