danjs · Answer

linear will always change the same amount per change in x,

danjs · Answer

slope of th eline

anonymous · Answer

what they said ^^^

danjs · Answer

Check if the slope stays constant... for any 2 points in the table,   the slope will be the same...

anonymous · Answer

thanks

danjs · Answer

if it is a linear set of points,  then use any of the two points , to get a slope,  and then construct the point-slope form for the line

$$\large (y-y_{1})=m*(x-x _{1})$$

for any point (x1,y1) in the table

danjs · Answer

Or since they give you the y-interept in the table   (the b, in y=mx+b    )   form of a line. 

just use that and the slope
