Answer:

The line would be a horizontal line through the point y = -2

The equation of the line would therefore be

y

=

−

2

Explanation:

If graph the point

(

0

,

−

2

)

we find that that point is on the y axis and therefore represents the y intercept.

If we then plug in the slope and y intercept into the slope-intercept formula of

y

=

m

b

+

b

where

m

=

the slope the

b

=

the y intercept, then

y

=

m

x

+

b

becomes

y

=

0

x

+

(

−

2

)

which simplifies to

y

=

−

2

Solution:

<u>Step-1: Find the slope of the line.</u>

  • Slope = Rise/Run = y₂ - y₁/x₂ - x₁
  • => -5 - (-5)/2 - 0
  • => -5 + 5/2
  • => 0/2 = 0

<u>Step-2: Find the y-intercept.</u>

When looking at point (0 -5), we can see that the x-coordinate is 0.

This means that:

  • The y-intercept must be -5.

<u>Step-3: Create the equation.</u>

  • y = (m)x + (b)
  • => y = 0x + (-5)
  • => y = -5

The proof that AMNS AQNS is shown.
FrozenT [24]

Answer:

The answer is "MS and QS".

Step-by-step explanation:

Given ΔMNQ is isosceles with base MQ, and NR and MQ bisect each other at S. we have to prove that ΔMNS ≅ ΔQNS.

As NR and MQ bisect each other at S

⇒ segments MS and SQ are therefore congruent by the definition of bisector i.e   MS=SQ

In ΔMNS and ΔQNS

MN=QN       (∵ MNQ is isosceles triangle)

∠NMS=∠NQS     (∵ MNQ is isosceles triangle)

MS=SQ         (Given)

By SAS rule, ΔMNS ≅ ΔQNS.

Hence, segments MS and SQ are therefore congruent by the definition of bisector.

The correct option is MS and QS

If you found the percent of a number and the product is greater than the number, whatvdo you know about the percent? Explain.
Ganezh [65]
The percent of said number must be over 100% because 100% is the whole value of a number

Ex:
105% of 20 is 21 because, 100% of 20 is 20 and 5% of 20 is 1
150% of 20 is 30 because, 100% of 20 is 20 and 50% of 20 is 10

Hope this helps

PLEASE HELP! The table shows the number of cans of soup shipped in different numbers of boxes.
mel-nik [20]
The equation that expresses the relationship between the number of boxes, b and the number or cans, c would be c = 48b. This is because the number or cans shipped would be the dependent variable to the problem as it is dependent on the number or boxes that ship along with. So if one ships 2 boxes then the number of cans that would be shipped would need to match the final output of cans which is 96, and using the equation, c = 49b it does.

c = 48b
96 = 48(2)
96 = 96.

Technically the first option will also be correct but usually the variable in an algebraic expression comes after the coefficient.
