A. What does the equation x=4 represent in R2? Whatdoes it represent in R3? Illustrate with sketches.

b. What does the equation y=3 represent in R3? Whatdoes z=5 represent? What does the pair of equations y=3 and z=5? Inother words, describe the set of points (x, y,z) such that y=3 andz=5. Illustrate with a sketch.

The first attached diagram is for the two dimensional graph

Where the two dimensional graph of x=4 is vertical line containing the coordinates of (4,0)

Second image attached is the three (3) dimensional Coordinate of x=4 is the vertical plane containing the line x=4 in xy-plane

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
