Answer:
have no idea lol im terrible at math
Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45
Answer:

Step-by-step explanation:
Answer:
4 sqrt(3) cm
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
48 = s^2
Take the square root of each side
sqrt(48) = sqrt(s)
sqrt(16*3) = s
4 sqrt(3) =s
