Answer:

D or answer 4                   y=-5/2x+7

Step-by-step explanation:

Well we can first start of by finding the y-intercept.

Note that when x=0, you can find your y-intercept.

Knowing this, and looking at the table, 7 is the y-intercept because when y=7, x=0.

So we can eliminate choices 'a' and 'c,' or answers 1 and 3, because they have the y-intercept as -7, when it's just 7.

Please know that in the equation:

y = mx + b

y = y-coordinate or any given point

mx = slope

b = y-intercept

Now we must find slope

To find the slope we need to do:

(y2 - y1) / (x2 - x1) or rise/run

The two coordinates I choose to use is (0, 7) and (6, -8).

(-8 - 7) / (6 - 0) = -5/2

-5/2 is the slope

Finally, look for an equation that has 7 as the y-intercept and -5/2 as the slope.

Answer: D or answer 4

Zolol [24]

Answer:

<u><em>Question 10.</em></u>

Length of the side of the square = \sqrt{441} = 21

By Pythagoras' Theorem,

Hypotenuse = \sqrt{21^{2} + 20^{2} } (H > 0)

                     = 29 m

Ans: 29 m

<u><em>Question 11.</em></u>

By Pythagoras' Theorem,

Length of longer side of 42 km = 42- \sqrt{18^{2} - 15^{2} } (L > 0)

                                                                     = 32.050 km (5 s.f.)

By Pythagoras' Theorem,

Length of the unknown side = \sqrt{32.050^{2} + 15^{2}  } (L > 0)

                                               = 35.4 km (3 s.f.)

Ans: 35 km

Let's make sure that the answer is right:

A= bh

A= 3(6)

A= 18
