3+5=5+3 TRUE
3·5 = 5·3 TRUE
The inverse addition of a number consists in adding the same numbers but with opposite signs, then, you have:

Answer:
y=2x-1
Step-by-step explanation:
straight line equation 
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2 
 use one the coordinates 
(2,3)
3=2(2)+c 
3=4+c
c=3-4
c = -1
y = 2x - 1
