Classify the system of equations 2x + y - 7 = 0 1/3 x + y - 4 = 0
a. coincident
b. intersecting
c. parallel

B

Step-by-step explanation:

The equations are:

2x + y - 7 = 0

and

1/3x + y -4 = 0

Let's rearrange the first to get:

y = -2x + 7

Putting this into the 2nd equation we get:

Now, y would be:

Solving the equation we see that there is 1 unique solution with 1 x value and another y values. That means, when graphing, the lines would intersect.

Answer choice B is right.

Note: Coincident means the same line and parallel means there would be no solution when solving

if this is really you s much. i only have 3 points left and i have 2 questions to ask
