Answer:
y = 1/4x -8
Step-by-step explanation:
First find the slope of the line
x-4y =3
Subtract x from each side
x-4y -x = -x+3
-4y = -x+3
Divide each side by -4
-4y/-4 = -x/-4 +3/-4
y = 1/4 x -3/4
This is in the form y= mx+b where the slope is m and the y intercept is b
The slope is 1/4
We want the same slope
y = 1/4x +b
we know the y intercept is -8
y = 1/4x -8
Answer:
Step-by-step explanation:
Angles in a straight line add up to 180°.
Angles in a triangle add up to 180°.
The probability of choosing a blue marble is 3/6 or 1/2 because 1/3 +1/6 equals 3/6. Meaning that only 3/6 is left over for blue's probability.
Substitution:
6y + 5x = 8
x + 3y = -7
x = -3y + 7
6y + 5(-3y + 7) = 8
6y - 15y + 35 = 8
-9y + 35 = 8
-9y = -27
-y = -3
y = 3
x = -7 + 9
x = 2
y = 3
x = 2
