Question

which linear equation best represents the data given in the table?
answers-
y=4x-3
y=3x+4
y=3x-4
y=4x+3

Answer 1

Take any 3 points
Lets take the first two
(-2,-2) and (-1,1)

First get slope a=Y-Y/X-X=-2-1/-2+1=3
Eq: y=3x+b
Substitute any point since they satisfy the equation: I will take (-2,-2)

y=3x+b
-2=-6+b
b=4




Overall eq: y=3x+4
