What is the equation of this line in slope-intercept form?

Mathematics

Sloan [31]3 years ago
3 0

The correct answer is A) y = -3x - 1

In order to find this, start by using the two points on the line to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-4 - 2)/(1 - -1)

m = -6/2

m = -3

Since A is the only one with a -3 slope, this is the correct answer.

A hotel offers two activity packages. One costs $192 and includes 3 h
poizon [28]

Let x = Horseback riding and y = Parasailing

Eq. 1

3x + 2y = 192

Eq. 2

2x + 3y = 213

By elimination:

<span>     2(3x + 2y = 192)</span>

+ -3(2x + 3y = 213)

<span>              -5y = - 255</span>

y = $ 51

Substitute y :

3x + 2y = 192

3x + 2(51) = 192

<span>x = $ 30
</span>


<span>Hope this answer will be a good help for you.</span>

A small explanation would be really appreciated​
shutvik [7]

Step-by-step explanation:

the 2 angles marked with orange and green are equal becos the question said that the indicated angles are congruent meaning same deg. so 180 - that given angle = the 2 marked angles (based on the rule known as angles on a str line are supplementary)

since the 2 marked angles are same, you can say that d and k are parallel due to the rule of alternate angles
