Find the equation of the line that passes through the following lines points (0,-1) and (3,12).​
Temka [501]

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

The ratio table below shows the relationship between the number of bricks in a wall and the length of the wall.
Elza [17]

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
