the number is 100
Step-by-step explanation:
1/4 of hundred = 25
2/4 of hundred = 50
3/4 of hundred = 75
4/4 of hundred = 100
D=y2-y1
D+y1= y2-y1+y1 add y1 to both sides to cancel it out.
D+y1=y2 that drops -y1 for the right side but the left remains.
And that's your answer.
The equation for line E is x = 8.
This is because the line intersects the x-axis at the point (8,0)
