Find the slope of the line

matrenka [14]

Answer:

Step-by-step explanation:

To find the slope of the line, use the equation:

slope = $\frac{y_2-y_1}{x_2-x_1}$

Let's find 2 obvious points on the line

(5,5) and (10,10)

Since (10,10) comes after (5,5), this will be our $(x_2,y_2)$

(5,5) will be our $(x_1,y_1)$

Let's Solve!

$\frac{10-5}{10-5} =\frac{5}{5} =1$

Therefore, our slope is 1

Plz solve, find the area for each one, and plz show ur work or explain what u did

Serga [27]

The area of the trapezoid is

$S=\frac{h(a+b)}{2}$

1) $S=\frac{7(6,2+3,8)}{2} =\frac{70}{2} =35ft^2$

Answer: S=35ft²

2) $S=\frac{12,6(10,3+15,1)}{2} =\frac{320,04}{2} =160,02in^2$

Answer: S=160,02in²

3) $S=\frac{8,9(4,4+5,7)}{2} =\frac{89,89}{2} =44,945yd^2$

Answer: S=44,945yd²
