Anyone please help me with last two I'll vote brainliest!! :))
Alja [10]

Answer:

7. y= x + 12   8. y= -1 + 4x

Step-by-step explanation:

for 7 all you need to do is subtract x from both sides to get y= 12- x, and to make it perpendicular you need to make the current slope it’s exact opposite so in this case that’s just changing the “-” symbol to an “+”.

for 8 you do the same first step you did in 7 and subtract 4x from both sides to get -y= 1 - 4x. Next you divide everything by -1 (because it’s the number in front of the Y) and you get Y= -1 + 4x

Xelga [282]
Solutions 

 8 over 12 minus 4 over 12 = \frac{8}{12} - \frac{4}{12}
Fractions have two parts. The denominator and the numerator<span>. 
</span>
The denominator in a fraction represents the total number of equal size pieces that make up a whole. For example 7/12 of a foot means one foot is broken into 12 equal sized divisions.

<span>The numerator in a fraction represents the number of pieces selected. If the numerator is larger than the denominator, the number is larger than one. For example, 15/12 of a foot is equivalent to. 

</span><span>A common denominator is needed when adding, subtracting and comparing fractions because each object needs to be cut into the exact same size pieces to be able to combine, remove or compare.  
</span>
\frac{8}{12} and \frac{4}{12 } have the same denominator. 

Solve 

8 - 4 = 4 

The denominator stay the same. 

<span>Answer = \frac{4}{12}</span>
