Slope intercept form is y=m(x)+b
M is the slope to find it you do the first y value minus the second y value and do the same for x
-6-2. 3+1
You then divide the subtracted y values by the subtracted x values
-8/4
M=-2
To find the b you plug in one set of the coordinates
-6=-2(3)+b
-6=-6+b
b=0
So the equation is
Y=-2x

PSYCHO15rus [73]

Answer:

  • 20 m

Step-by-step explanation:

<u>We have similar triangles here.</u>

  • BC║DE, AB║AD and AC║AE ⇒ ΔADE ~ ΔABC

<u>The ratio of corresponding sides of similar triangles is same:</u>

  • BC/DE = AC/AE
  • BC / 2 = 30/3
  • BC / 2 = 10
  • BC = 2*10
  • BC = 20 m

When a whole number is multiplied by a decimal smaller than one, what can you conclude about the result?
Sophie [7]

Answer:

The answer is D

Step-by-step explanation:

  1. The resulting number is smaller than the original. This is true because if you take 20 times 0.5 it will equal ten. A decimal is pretty much a fraction in another form.

  • The reason why A is false is because if the number isn't being multiplied by 1 then it can't stay the same.
  • The reason why B is false is because that is not true as in the example above, 20 times 0.5, it equaled 10 and not less than one.
  • The reason why C is false is because the the resulting number simply cannot be higher than the original when being multiplied by a decimal smaller than 1.

Hope this helps
