Answer:
equation of line is:
y = -2x - 6

Explanation:
The general form of the line is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept

(a) getting the slope of the line:
slope of the line is calculated using the following rule:
slope of line (m) = (y2-y1) / (x2-x1) = (-24--12) / (9-3) = -2
The equation now becomes:
y = -2x + c

(b) getting the y-intercept:
The two given points belong to the line. Therefore, to get the y-intercept, we will use one of the points and substitute in the equation and solve for c.
I will use the point (3,-12)
y = mx + c
-12 = -2(3) + c
-12 = -6 + c
c = -12 + 6
c = -6

Based on the above, the equation of the line is:
y = -2x - 6

Hope this helps :)

Step-by-step explanation:

-2x = 18 - 4x

-2x + 4x = 18

2x = 18

x = 18/2

x = 9

HELP PLEASE WITH PART A AND B!!!!!
Elden [556K]
<h2>a. Answer:</h2>

For this question we'll use the following method:

1. Let's subtract old value from new value

185$-160$ = -25$

The negative value implies that the price has decreased

2. Divide the result by the old value

25$/185$ = 0,1351

3. Convert this value to percentage:

0,1351 x 100 = 13,51%

Finally, by rounding to the nearest tenth:

13,5%

That means 13,5% decrease

<h2 /><h2>b. Answer:</h2>

1. Let's subtract old value from new value

77$-56$ = 21$

The positive value implies that the price has increased

2. Divide the result by the old value

21$/77$ = 0,2727

3. Convert this value to percentage:

0,2727 x 100 = 27,3%

Finally, by rounding to the nearest tenth:

27,3%

That means 27,3% increase

-3/4x+5/6y=15<br>x-intercept=<br>y-intercept=
Trava [24]

To make this easier, you need to change the fractions by multiplication.

-3/4x=15 - First, you multiply 4 to both sides of the equation

(4)-3/4x=15(4)

-12/4x=60 - Simplify

-3x=60 - Divide by -3 on both sides

x=-20 -> (-20,0)

Do the same to find the y-intercept, to get (0,18)
