Question

Application problem with a linear function: Finding a coordinate given two points

Answer 1

really need more information

but plowing ahead

say, you have 2 points (1,2) and (2,3) then the linear function is y=mx +b with m = 1, and

y = x +b and 2 = 1+b so b= 1

linear function is y =x+1 where 1 is the y coordinates of the y intercept (0,1)
