3. one of the graphs represents
3x +2y < -6
3x + 4y > -12

where would u shade on a graph?

3x-2y=6

Step-by-step explanation:

Subtract 3x from both sides of the equation

Divide each term by −2 and simplify.

y=-3+

Rewrite in slope-intercept form

y=

Use the slope-intercept form to find the slope and y-intercept.

Find the values of m and  b using the form y=mx+b

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope:

y-intercept: -3

Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding  y values.

Choose 0 to substitute in for x to find the ordered pair.

(0,−3)

Choose 1 to substitute in for x to find the ordered pair.

Graph the line using the slope and the y-intercept, or the points.

slope:

y-intercept:-3

2 is the final ! : )

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
