Sagot :

Equation (1) ,(2),and (3) are the form of linear equation.


A linear relationship (or linear association) is a statistical term used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b.
(1). 5+2y= 13
2y=13-5
2y= 8
y=4.
So this is the form of mx+b
Where b=4 and x=0.
(2). y = x²³+7
It is the form of mx+b .
where mx = x²³ and x=7

(3). y-5= 2(x-1)
y-5 = 2x-2
y=2x-2+5
y=2x+3
It is completely the form of mx+b .
where m= 2 and b = 3.
