Find the area of a polygon with vertices at (1,3), (7,3), (7,7), and (4,7).
Natasha2012 [34]

(1,3) and (7,3) falls on the same horizontal line. hence, the distance is just equal to 6 units. (7,3) and (7,7) meanwhile lie on the same vertical line. hence the distance is 4. (7,7) and (4,7) lie on the same horizontal line with a distance of 3. 

Finally, to get back to point (1,3) - (4,7) ----> (1,3), 3 to the left and 4 down, the diagonal being 5. 
6+4+3+5= 10 + 8 = 18.

What is the slope of the line through (- 1, - 7) and (3, 9) ?
Fynjy0 [20]

Answer:

C. 4

Step-by-step explanation:

<u>Use the slope formula:</u>

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

m = the slope.

<u>Substitute the values into the formula:</u>

\frac{9}{3} -\frac{-7}{-1} =\frac{?}{?}

<u>Solve:</u>

\frac{9}{3} -\frac{-7}{-1} =\frac{16}{4}

<u>Simplify 16/4:</u>

\frac{16/4}{4/4} =\frac{4}{1}=4
