Question

(8.02 LC)

Four equations are graphed on the coordinate grid:

A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Line A passes through the ordered pairs negative 8, 5 and 4, negative 7. Line B passes through the ordered pairs negative 3, 8 and 2, negative 7. Line C passes through the ordered pairs 0, 9 and negative 7, negative 5. Line D passes through the ordered pairs 1, 4 and negative 4, negative 1 and is extrapolated further in the quadrant.

Which set of equations has (−4, 1) as its solution?

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

Answer 1

First we graph the given points and join them to form lines A,B,C,D as described in the question. Now we can easily check point (-4,1) lies on which line.

From graph we see that test point (-4,1) lies only on lines A and C.

Hence equatin of lines A and C will be final answer.
