Consider the linear equation 2x - 3y = -12 graph the points
levacccp [35]

The graph of linear equation 2x - 3y = -12 is as shown below.

I this question, we have been given a linear equation 2x - 3y = -12

We need to graph the points.

For x = 1,

2(1) - 3y = -12

2 - 3y = -12

-3y = -14

y = 14/3

For x = 0,

2(0) - 3y = -12

y = (-12)/(-3)

y = 4

For x = -1,

2(-1) - 3y = -12

-3y = -12 + 2

y = (-10) / (-3)

y = 10/3

So, we get coordinates (1, 14/3), (0, 4) and (-1, 10/3)

Now we plot these points.

The graph of linear equation 2x - 3y = -12 is as shown below.

Please help! It’s not too hard! Will mark brainliest!
Yuki888 [10]

Step-by-step explanation:

In the first part, he was travelling with twice the speed, or Vs, for distance

48 - d, for 2 hours.

speed = distance/time

distance = speed * time

First part :

48 - d = 2V * 2

⇒d + 4V = 48  

Second part:

d = V * 2

⇒d = 2V  

Substitute 2s for d in equation 1.

2s + 4s = 48

6s = 48

s = 8

The speed in the second part is 8 mph.

<u>The speed in the first part is 2s = 2(8) = 16</u>

I hope this helps
