. Find the slope of the line containing the points (3,-7) and (4,-9).

m=-2

Step-by-step explanation:

the formula for slope (m) is (y2-y1)/(x2-x1)

the given points are (3,-7) and (4,-9)

label the points;

x1=3

y1=-7

x2=4

y2=-9

substitute into the equation:

m=(-9--7)/(4-3)

m=(-9+7)/(1)

m=-2/1

the slope is -2

hope this helps!

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
