Q1: Find the slope of the line passing through the pairs of points and describe
the line as rising, falling, horizontal or vertical.
(-1,0),(3,-5)

slope = - 1.5

line is falling

Step-by-step explanation:

slope = (y-y') / (x-x') = (-5 - 0) / (3 - (-1)) = -5 / 4 = - 1.5

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
