What is the slope of the table x= 2, 0, -2, -4 y= 6, 1, -4, -9

Murrr4er [49]

Answer:

The slope of the table is $m=\frac{5}{2}$ or $m=2.5$

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the following ordered pairs

(2,6),(0,1),(-2,-4) and (-4,-9)

take two points

(2,6) and (-4,-9)

substitute in the formula

$m=\frac{-9-6}{-4-2}$

$m=\frac{-15}{-6}$

simplify

$m=\frac{5}{2}$

To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. You then use the regular polygon area formulas to find the area of each of those polygons. The last step is to add all those areas together to get the total area of the irregular polygon
