system of linear equation
step-by-step explanation:
as given in the data
a= 20 , b= -12
let us suppose that it is a straight line equation
now we know the formula for the system of linear equation
b= ma + c )
here m is slope of a straight line which is equal to formula
m= (ii)
and here c is a constant
now putting the value of a and b in equation (ii)
m=
m=
putting the value of a,b and m in equation (i) gives us
-12 = + c
-12=-12 + c
adding 12 to both sides
-12 +12 = -12 +12 +c
0 =c
or c=0
as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
