Answer:
First number: 71/7
Second number: 135/7
Third number: 270/7
Step-by-step explanation:
First number = x
Second number= 2x-1
Third number= 2(2x-1)
x+(2x-1)+2(2x-1)= 68
3x-1+4x-2=68
7x-3=68
7x=71
x=71/7

Answer:
y=-9/2x-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-8)/(-2-(-4))
m=-9/(-2+4)
m=-9/2
y-y1=m(x-x1)
y-8=-9/2(x-(-4))
y-8=-9/2(x+4)
y=-9/2x-36/2+8
y=-9/2x-18+8
y=-9/2x-10
