Find the slope of the line
matrenka [14]

Answer:

1

Step-by-step explanation:

To find the slope of the line, use the equation:

slope = \frac{y_2-y_1}{x_2-x_1}

Let's find 2 obvious points on the line

(5,5) and (10,10)

Since (10,10) comes after (5,5), this will be our (x_2,y_2)

(5,5) will be our (x_1,y_1)

Let's Solve!

\frac{10-5}{10-5} =\frac{5}{5} =1

1

Therefore, our slope is 1

one bricklayer can build a wall in 6 hours. another bricklayer could build the same wall in 4 hours. if they work together, how
kogti [31]
Hello,

Let's
V1 the velocity of the 1st bricklayer,
V2 the velocity of the 2nd bricklayer,

1wall=V1*6==>V1=w/6
1wall=V2*4==>V2=w/4
==>V1+V2=w/6+w/4=10w*24=5w/12

Let's t the time for the 2 bricklayer to build the wall
(V1+V2)t=w
==>5w/12*t=w
==>t=12/5 (h)=2h24min.
