To find the area of a parallelogram, you simply have to multiply the base and the height. The formula is "A = bh." So, multiply 8 and 4, and you'll get 32. The area of this parallelogram is 32ft.
Answer:
y= 2x -9
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.

Slope



= 2
Substitute m= 2 into the equation:
y= 2x +c
To find the value of c, substitute a pair of coordinates.
When x= 4, y= -1,
-1= 2(4) +c
-1= 8 +c
c= -1 -8
c= -9
Thus, the equation of the line is y= 2x -9.
1/9 is your answer because you have to do the reciprocal. Then you make 1 2/3 to a mixed fraction. Then you multiply.
