What is the equation of the line that passes through points (4,2) and has a y-intercept of -2?

Question

Y=Mx+B

y=mx+b

y=mx+b

y=mx+b

Answer 1

    y    =    m x        +     b

             m is slope        b is y-intercept (the place where x=0

 

We have two points:     (0,-2) and (4,2)

   The slope, m, (rise over run) is 4/4 = 1

 

 The equation is:    y = x - 2
