A line has a slope of 2 and contains the points (1, 3) and (2, y). The value of y is

Question

I just need help with this question

Answer 1

y=mx+b

y=2x+b

point (1,3)

substitute to find b

3=2*1+b

3=2+b

b=1

equation is y=2x+1

point (2,y)

substitute to get y

y=2*2+1

y=4+1

y=5

point (2,5)
