Answer:
y=13/3x-1
Step-by-step explanation:
k=(y2-y1) /(x2-x1)
A(0,-1) x1=0,y1=-1
B(3,12) x2=3, y2=12
k=(12-(-1))/(3-0)
k=(12+1)/3
k=13/3
y-y1=k(x-x1)
y-(-1)=13/3(x-0)
y+1=13/3*x
y=13/3*x-1
Answer:
When number of bricks is multiplied by 2, the length is multiplied by
B) 2
Step-by-step explanation:
Number of bricks is two times the length of the wall
i.e. Number of bricks= 2×Length of the wall
When the number of bricks is multiplied by 2, the length is also multiplied by 2
since, when number of bricks=6 then, length of wall=3
and when number of bricks=2×6=12 then, length of wall=2×3=6
Hence, when number of bricks is multiplied by 2, the length is multiplied by
B) 2
Answer:
