Answer:

The line passing through points (1,4) and (4,3).

The line passing through points (1,-4) and (4,-5).

Step-by-step explanation:

Since the equation is y=3x+1

If it was perpendicular, it means the slope would be the negative reciprocal.

So the slope would be -1/3

9-8/6-3=1/3 (not negative) <u>No</u>

3-4/4-1=-1/3 <u>Yes</u>

-5+4/4-1=-1/3 <u>Yes</u>

6-3/5-4= 3/1 <u>No</u>

mrs_skeptik [129]

Answer:

y = - 3x - 2

Step-by-step explanation:

Step 1:

y = mx + b     Slope Intercept Form

Step 2:

y = - 3x + b     Input Slope

Step 3:

4 = - 3 ( - 2 ) + b     Input x and y

Step 4:

4 = 6 + b     Multiply

Step 5:

- 2 = b       Subtract 6 on both sides

Answer:

y = - 3x - 2

Hope This Helps :)

(1,5) , (2,6) , (3,7) , (4,8) , (5,9)....these are the 5 points

  x               f(x)
  1                5
  2                6
  3                7
  4                8
  5                9

domain (ur x values) is { 1,2,3,4,5}
range (ur f(x) or y values) is { 5,6,7,8,9}

Is ur relation a function : yes, it is a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.

pickupchik [31]

Answer:

Part 1

If the actual park is 250 yards LONG, I think it means that its LENGTH is also 250 yards

Part 2

It's a proportion:

5=x

7=250

5*250:7=178.6 yards

The area is 178.6 yards wide and 250 yards long
