You take a fraction for example,6/12 and you find the GCF of both numbers in this case it would be 6 because 6 is the GCF.I hope this helps
Answer:

Step-by-step explanation:
In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.

Using the formula above,




Substitute the value of m into the equation:

To find the value of b, substitute a pair of coordinates into the equation.
When x= 2, y= 5,

5= 3 +b
b= 5 -3
b= 2
Thus, the equation of the line is
.
So first we solve and simplify

9-4(x-y)=-6x+6
distribute using distributeive property of multiplication which is a(b+c)=(ab)+(ac)
so -4(x-y)=-4x+4y
9-4x+4y=-6x+6
add 6x to both sides
9+2x+4y=6
subtract 9 from both sides
2x+4y=-3
only B matches this
B is the correct answer
(I don't know what standard form is but I know what simplified is)
