Respuesta :

great, with the graph and the line equation

y=mx+b

m is the slope and b is, in this case, b= 4 (where the line cross the x=0)

so know we have y=mx+4

we know the line cross over the point x=2 y=0

so if we replace it on the equation we will find the slope

0=m*2+4

-4=m*2

-4/2=m

m=-2

the answer is m= -2
