**Answer 1**

Answer:

Water level and temperature

Step-by-step explanation:

Scatter plots are used to graph linear data containing to two variables, with the independent variable on the x - axis and the dependent variable on the y-axis. Linear data graphed on a scatter plot may be positive or negative depending on the type of relationship which exists between the two variables. Positive relationships are represented by positive slopes, with x increasing as y increases. Negative relationship on the other hand results in a reduction in Y as X increases and vice versa. Examples of negative correlation include the association between water level and temperature. ; water level will usually decrease as temperature rises. Therefore, any association between variables whereby a increase in one leads to a corresponding decrease on the other is tagged as a negative correlation.

I have a question. It is: 5x+2y=4 3x+6y=-12 Solve the system of equations by graphing. How do I input that on a Casio graphing calculator. Giving brainliest if it works. Thanks!

### Answers

**Answer:**

**Step-by-step explanation:**

** [1] 5x + 2y = 4**

** [2] 3x + 6y = -12**

**Graphic Representation of the Equations :**

** 2y + 5x = 4 6y + 3x = -12 **

// Solve equation [2] for the variable y

[2] 6y = -3x - 12

[2] y = -x/2 - 2

// Plug this in for variable y in equation [1]

[1] 5x + 2•(-x /2-2) = 4

[1] 4x = 8

// Solve equation [1] for the variable x

[1] 4x = 8

[1] x = 2

// By now we know this much :

x = 2

y = -x/2-2

// Use the x value to solve for y

y = -(/2)(2)-2 = -3

How do you find a slope and the Y intercept

### Answers

**How to find slope:**

Divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

The actual formula for this is: (y2 - y1)/(x2 - x1).

**How to find Y intercept**

To find the y-intercept, plug 0 in for 'x' and solve for 'y'.

Ex. 2x + 3y = 12

So you plug in 0 for x therefore it becomes:

3y = 12

so, the y intercept is 4

0.225989

**Answer:**

=78 degrees

**Step-by-step explanation:**

complementary angles add up to 90 degrees

A + B = 90

3x + 9 + x - 11 = 90

3x + x + 9 - 11 = 90

4x - 2 = 90

collect like valuables

4x = 90 + 2

4x = 92

x =23

angle A = 3x + 9

= (3 x 23) + 9

= 69 + 9
