Answer:

Negative

If the the line goes from quadrant 2 to quadrant 4 then the slope would be negative

to find the slope you take

Δy÷Δx .... this just means the change in y over the change in x

for example

if i had points A (-2,3) B( 4,-5)

I take the y points and subtract them from one another

and i then take the x coordinates and subtract them, take the end result and divide y over x

3-(-5) / -2-4

8/-6

4/-3

And since the final slope is negative therefore the line is going downwards and is negative

Answer:

1) 40
2) C. 22.5

Step-by-step explanation:

<u>The ratios of corresponding sides of similar figures are equal:</u>

x / 25 = 24 / 15
x / 25 = 8 / 5
x = 25*8/5
x = 40

<u>Short sides are x and 15, long sides are 36 and 24. The ratios are same:</u>

x / 15 = 36 / 24
x / 15 = 3/2
x = 15*3/2
x = 22.5

Correct choice is C
