How will the graphs of (8x-12y=20) and (2x-3y=5) be?

Answer and explanation

Correct answer: Coincident

The direct answer is option C: the graphs are coincident, meaning they are the same line. Compare the equations 8x-12y=20 and 2x-3y=5. Dividing every term of the first equation by 4 gives 2x-3y=5, exactly the second equation. Multiplying or dividing a whole linear equation by a nonzero number does not change its graph. Therefore every point on one line lies on the other, so there are infinitely many common solutions. A, parallel and distinct, is wrong because distinct parallel lines have different equations after simplification and no common point. B, intersecting at one point, is wrong because that would produce one common solution, not identical equations. D, intersecting at the origin, is wrong because the origin (0,0) does not satisfy 2x-3y=5; its left side is 0, not 5. Coincident lines are visually one line drawn twice. Memory cue: simplify both equations first; identical simplified equations mean coincident lines.
