Answer:
since 2 out of every 5 marbles is blue, 4 tenths of the marbles are blue so 40% is blue. not 50
X - y = 2
4x - 3y = 11.
Using Elimination method, eliminating x, multiply equation (i) by 4. Because of the 4 in the second equation.
x - y = 2 ... (x4)
4x - 3y = 11.
4x - 4y = 8
4x - 3y = 11.
The first minus the second.
(4x - 4x) -4y- -3y = 8-11
-4y + 3y = -3
-y = -3. Divide both sides by -1
y =3.
Substitute this value into the very first equation
x - y = 2, y = 3
x - 3 = 2
x = 2 + 3 = 5.
Therefore x = 5, y = 3.
A negative slope makes a line go down to the right.
The line C goes up to the right, so that is not it.
slope = -5 = rise/run = -5/1
For every 5 the y-coordinate goes down, the x-coordinate goes 1 to the right.
Only line B goes down 5 and right 1, so the answer is line B.
Answer: Line B
