a number is multiplied by 8 and that product is added to 2. The sum is equal to the product of 2 and 25 . Find the number

6

Step-by-step explanation:

So we have a number (let's call it x) and it was multiplied by 8 and added by 2. Therefore:

And we are told that the sum is equal to the product of 2 and 25 (or 50). Thus:

To find the number, we just need to find x. Thus, subtract 2 from both sides:

Divide both sides by 8:

And we're done!

So, our original number was 6.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
