Answer: The slope is undefined  

Step-by-step explanation:

The slope of a line is calculated using the formula :

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

x_{1} = -7

x_{2} = -7

y_{1} = -7

y_{2} = 1

Substituting the values into the formula , we have :

m = \frac{1-(-7)}{-7-(-7)}

m = \frac{8}{0}

m = undefined

in the bag, there are certain number of toy- blocks with alphabets A,B,C and D written on them. The ratio of blocks A:B:C:D is 4
Svet_ta [14]
Given, the ratio of blocks A, B, C,D are in the ratio 4:7:3:1

Let us consider the common ratio to be ‘x’.

So, toy blocks with alphabet A is 4x and

toy blocks with alphabet B is 7x and

toy blocks with alphabet C is 3x and

toy blocks with alphabet D is x


Again, the number of ‘A’ blocks is 50 more than the number of ‘C’ blocks.

As no. of ‘A’ and ‘C’ blocks are 4x and 3x respectively.

So,

4x=50 + 3x

x=50

Thus, the number of ‘B’ blocks is 7x = 7(50) = 350

350 is the required number.
