Which graph represents the system of equations –3x + y = 3 and –x + 2y = –4? On a coordinate plane, 2 lines intersect at (3, 0).
On a coordinate plane, 2 lines intersect at (negative 2, negative 3).
On a coordinate plane, 2 lines intersect at (negative 1.5, 1).
On a coordinate plane, 2 lines intersect at (1.5, 2.5).

The correct answer is B

Step-by-step explanation:

if x decreases by 4 then y increases by 10

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
