Answer:
y=-2x+4
Step-by-step explanation:
The equation of the line is:
y=mx+b
m= slope= (y2-y1)/(x2-x1)
we have two points giver from the graph:
point 1: (1,2)
point 2: (4,-4)
we to find the slope:
m=(-4-2)/(4-1)
m=-6/3
m=-2
we need to find "b"
using the point (1,2)
we have:
2=-2*(1)+b
2=-2+b
so we have b=2+2=4
finally we have that the answer is:
y=-2x+4
