Question

The coordinate grid shows the graph of four equations:

Which set of equations has (1, 2) as its solution?

A A and D
B C and D
C A and C
D B and D

plz help meeeeee ❤❤❤

Answer 1

Answer: A and C

Explanation:

Step 1 is to locate the point (1,2). You start at the origin, then move 1 unit to the right and 2 units up. Alternatively, you can draw a vertical line through 1 on the x-axis and a horizontal line through 2 on the y-axis. The horizontal and vertical lines cross at (1,2)

Step 2 is to then determine which lines go through (1,2). The two lines in question are line A and line C. So the intersection of line A and line C is the point (1,2). This point satisfies the equations that make up these lines. So that is why it is considered a solution to just these two equations only (ignore the other lines).

Hope this helps you I got it right on the test FLVS.

Answer 2

Answer: 3rd answer choice; A and C

Step 1 is to locate the point (1,2). You start at the origin, then move 1 unit to the right and 2 units up. Alternatively, you can draw a vertical line through 1 on the x axis and a horizontal line through 2 on the y axis. The horizontal and vertical line cross at (1,2)

Step 2 is to then determine which lines go through (1,2). The two lines in question are line A and line C. So the intersection of line A and line C is the point (1,2). This point satisfies the equations that make up these lines. So that is why it is considered a solution to just these two equations only (ignore the other lines).
