sergij07 [2.7K]

triangle, trapezoid, triangle, parallelogram, rectangle and parallelogram

The area of triangles = 1/2 * base * haight.

Area of the parallelograms = height * base.

Area of rectangle= width * length

Area of trapezoid = 1/2 * (a + b) * height where a and b are the opposite parallel sides

The perimeters = sum of the sides of the polygons.

I NEED HELP !!!!!!!!!!!!!!!!!!!!!
cricket20 [7]

you must substitute x in the equation given :)

examples:

when x is -2

therefore, y = 2(-2) + 3

y = -1

when x is 0

therefore, y = 2(0) + 3

y = 3

when x is 1

therefore, y = 2(1) + 3

y = 5

when x is 3

therefore, y = 2(3) + 3

y = 9

for (b) you only have to plot based on the table ;)

hope this helps
