Please do number 2 please

The answer is -3

Y=mx+c

(4,2), (3,5)

answer is -3

Step-by-step explanation:

4=x1 and 2=y1

3=x2 and 5=y2

y2-y1/x2-x1

5-2/3-4

3/-1 or -3

since we are finding the slope,we have to minus the y2 from the y1 over the x2-x1 and we minus then simplify.

1. 8

2. 9

3. 20

4. 3

5. 17

6. 2.2

7. 11.25

8. 1

9. 14

10. 2

step-by-step explanation:

thats the first half

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
