Eliminate the parameter.
x = t2 + 3, y = t2 - 2

y = x - 5

Step-by-step explanation:

"Eliminate the parameter" means we want to eliminate the extra variable and rewrite it ias one equation that only contains x, y, and possibly a constant.

The extra variable in the equations is "t".  Manipulate one of the equations to solve for t². Then substitute t² = it into the other equation.

x = t² + 3         →          x - 3 = t²

y = t² - 2

y = (x - 3) - 2

y = x - 5

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
