Question

Choose the system of equations which matches the following graph. MULTIPLE CHOICE

Answer 1

5x + 2y = –14
7x + y = 7

5x + 2y = –14
7x – y = 7

5x – 2y = –14
7x + y = 7

5x – 2y = –14
7x – y = 7

Answer 2

i would change all the equations to the standard slope form y = mx + b (where m is the slope and b is the y intercept)

both the lines cut y-axis at -7 so look for the one that have y intercept = -7

Answer 3

y = 5/2x - 7
y = 7x + 7

Answer 4

y = 5/2x - 7
y = -7x - 7

Answer 5

y = -5/2x + 7
y = 7x + 7

Answer 6

for the first one it shuold be
y = -5x/2 - 7
y = -7x + 7

Answer 7

y = -5/2x + 7
y = -7x - 7

Answer 8

the 2nd one should be
y = -5x/2 - 7
y = 7x -7

you got the signs all wrong o.O

Answer 9

3rd one:
y = 5x/2 + 7
y = 7x + 7

Answer 10

mannn

Answer 11

haha, anyway 4th one
y = 5x/2 + 7
y = 7x - 7



now look at all 4, see which one have y-intercept = -7

(hint: y = mx + b, b is the y-intercept)

Answer 12

i believe the answer is B

Answer 13

because both equations have a y intercept of -7 and on the graph the two lines intersect at 0,7

Answer 14

ya. intersect at (0, -7)

be careful with the signs next time :P
b is correct

Answer 15

thank you!
