What is the slope of a line through (1,9) and (-3, 16)

The slope of the line is -7/4.

The formula for slope is:

lets say (1,9) 1 is x1 and 9 is y1

             (-3,16) -3 is x2 and 16 is y2

which equal

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
