Three points 4

The line passed through three points - see table:

x y
-6 4
-4 3
-2 2

Write line equation in y=mx+b form

Result

f = (Correct answer is: -0.5x+1) Wrong answer

Solution:

f(x)=mx+b   <÷class=alertalertdanger>Systemofequationsarenonlinear.</÷><÷class=alertalertdanger>Sorry,equation/equationsdonothaveanintegersolution...Pleasecheckthem.</÷>f(x)=0.5x+1  f3=0.5 (2)+1=2  f=0.5x+1=12f(x)=mx+b \ \\ \ \\ \ \\ <\div class='alert alert-danger'>System of equations are non-linear.</\div> <\div class='alert alert-danger'>Sorry, equation/equations do not have an integer solution ...
