y= -0.25x+2

Step-by-step explanation:

y = mx + b \\  \\ m =  \frac{rise}{run}  =  \frac{ - 1}{4}  \\  \\ b = where \: the \: line \: hits \: y \: axis = 2 \\  \\ y =  -  \frac{1}{4} x + 2

How do you solve a linear equation
Olenka [21]
It is hard to explain without a picture. You have the line graph and depending on what your numbers are, you place them where the teacher, (or paper) says too. You would then move two to the right, and one up. You would keep repeating that pattern until you got to the top of the graph. After that you would draw a strait line through it. If you are dealing with negative numbers, then depending on which one is negative, you would move two to the LEFT from the starting point and go one up. You repeat that pattern as well, then once you reach the top of the page you draw a line through it.
I hope this helped!

Eric wants to get an output of 0. Can he do this with each machine? If so, how? If not, why not?
natita [175]

Answer:

  • <u>No, he can get an output of 0 with the second machine (function B) but he cannot get an output of 0 with the first machine (function A).</u>

Explanation

The way each machine works is given by the expression (function) inside it.

<u>1)  </u><em><u>Function A</u></em>

To get an output of 0 with the function y = x² + 3, you must solve the equation x² + 3 = 0.

Since x² is zero or positive for any real number, x² + 3 will never be less than 3 (the minimum value of x² + 3 is 3). So, it is not possible to get an output of 0 with the first machine.

<u>2) </u><em><u>Function B</u></em>

Solve y=\sqrt{x}-2=0

  • \sqrt{x}-2=0

  • \sqrt{x} =2

  • x=2^{2}

  • x=4

So, he can get an output of 0 by using x = 4.
