Choose the best graph that represents the linear equation:<br> 6x = y + 8
Agata [3.3K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope

b: It is the cut point with the y axis

We have the following equation:

6x = y + 8\\y = 6x-8

Thus, the cut point with the y axis is -8. Therefore, we discard options C and B.

It is observed that the slope is positive so the correct graph is option B.

Answer:

Option B

Help please will mark brainliest!!!
Daniel [21]

Answer:

45°

Step-by-step explanation:

Well, compared to 90°, it looks like it's just smaller, but not too small. It couldn't be 15° degrees, or 60°, as it was probably too much. I Don't think it's 30° either,  because it looked bigger than what a 30° angle would be.

Hope it helped!
