Step-by-step explanation:
39500 x 103 = 4,068,500
in scientific notation, that ia 4.0685 x 10⁶
Y=mx+b
m=slope, b=y-intercept
m=(y2-y1)/(x2-x1), b=value of y when x=0
m=(3--1)/(-2-4)
m=4/-6
m=-2/3, now we have:
y=-2x/3+b, we can solve for b using any point, I'll use (4,-1)
-1=-2(4)/3+b
-1=-8/3+b
-3/3+8/3=b
5/3=b so
y=-2x/3+5/3
3 7 is the answer I hope this helps
