The length of the rectangle is 4
The width of the rectangle is 3.
The area of the rectangle is 12 square units.
Explanation:
Given that the coordinates of the rectangle are A(3,0), B(0,0), C(0,4), D(3,4)
We need to determine the length, width and area of the rectangle.
<u>Length:</u>
After plotting the coordinates in the graph, it is obvious that the length of the rectangle is 4.
<u>Width:</u>
After plotting the coordinates in the graph, it is obvious that the width of the rectangle is 3.
<u>Area of the rectangle:</u>
The formula to determine the area of the rectangle is given by
Substituting the values, we have,
Thus, the area of the rectangle is 12 square units.
Sorry for the confusion, redoing my answer for you!
Using the points (9/2,1), (-7/2,7)
m=y2−y1 over x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=7−(1) over −72−(92)
simplify
m=−3/4
Use the slope −3/4 and a given point (9/2,1) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1)
y−(1)=−3/4⋅(x−(9/2))
Rewrite in y=mx+b
solve for y
y=−3x/4+35/8
ill use desmos to graph (y=−3x/4+35/8)
