(3,16) and (6,19) if a problem has this written in it which ones would be x and which would be y? it says put it in this form. y=mx+b

Hi, I am very happy to help you! I know how to do this! Super Easy

You will have 2 different x's and they are 3 and 6.

You will have 2 different y's and they are 16 and 19.

In order to get m, you have to subtract y2-y1/x2-x1=m

So the answer would be 1.

In order to solve b, you have to choose one of your given coordinate points and plug them in for x and y and plug in your m, which is 1.

I will be choosing the coordinate points (3,16)

So our b is 13.

So our answer using the form is y=1x+13

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
