Answer:
Step-by-step explanation:
1. find the slope (m)
m=y2-y1/x2-x1
m=6-3/-1-2
m=3/-3
m=-1
2. y-y1=m(x-x1)
y-3=-1(x-2)
y-3=-1x+2
y=-1x+2+3
y=-1x+5
Y = mx + b
slope(m) = 3/4
(-8,7)...x = -8 and y = 7
now we sub and solve for b, the y int
7 = 3/4(-8) + b
7 = - 6 + b
7 + 6 = b
13 = b
so ur line is : y = 3/4x + 13
X times 4. x + x + x+ x. x would be the length of each side
Answer:
-2
Step-by-step explanation:
substitute:
(10 + 6)÷4(-2)
= 16÷-8
-2
