Respuesta :

Answer:

y = [tex]\frac{7}{2}[/tex]x + 2

Step-by-step explanation:

m= 2-9/ 0-2 = [tex]\frac{-7}{-2}[/tex] = [tex]\frac{7}{2}[/tex]

y=mx+b              9 = [tex]\frac{7}{2}[/tex] (2) + b

m= [tex]\frac{7}{2}[/tex]                   9 = 7 + b

b = 2                 -7   -7  

                          2 = b

y = [tex]\frac{7}{2}[/tex] x + 2
