Answer:
Explained Below
Step-by-step explanation:
first we need to turn the equation into point slope form.
3x + 4y = 12
4y = -3x + 12
y = -0.75 + 3
Parallel lines don't have a change in slope because they run parallel. Your answer would be -0.75 or -3/4.
.333 translated to a fraction would be one-third or 1/3
Answer:
A proportinal relationship can be represented in different ways. For instance, a ratio table, a graph of astraight line though the origin, also an equation of the form y=mx, where m is constant in proportinality.

Step-by-step explanation:
1) 5a+4b-3a-7b+4a
Add terms having 'a' and 'b' separately
=6a-3b
Now subtitute values of a and b :
=6(-3)-3(4)
=-18-12
=-30
2)c(6-b)-c²
=6c-bc-c²
Subtitute values of b and c:
= 6(-2)-(5)(-2)-(-2)²
=-12+10-4
=-6
3)5x²-2xy+3y
Subtitute values of x and y:
=5(-5)²-2(-5)(-2)+3(-2)
=5(25)-20-6
=125-20-6
=99
4)-k²-(7k-4m)
Subtitute values of m and k:
=-(-2)²-{7(-2)-4(4)}
=-4-(-14-16)
=-4-(-30)
=-4+30
=26
5)3(6x+5y)-2y
Subtitute values of x and y:
=3{6(3)+5(-3)}-2(-2)
=3(18-15)+4
=3(3)+4
=9+4
=13
6)5(3m-n)-4(2m-n)
Subtitue values of m and n:
=5{5(-8)-(-11)}-4{2(-8)-(-11)}
=5(-40+11)-4(-16+11)
=5(-29)-4(-5)
=-145+20
=-125
Note:If you have any question about it you can friendly ask.Thanks
Since there are no decimals this number can't be done
