Question

Which system has a solution in which the x value is greater than one?




y = 3x + 2 and y = 3x - 3

y = -2/3 x and y = -1/4 x + 1

y = 3x + 2 and y = -1/4 x + 1

y = 3x - 3 and y = -1/4 x + 1

Answer 1

@katiek3455654 Any idea which system it is?

Answer 2

Or, guess as to which option is the one.

Answer 3

The equations in the first option have the same slope and different y-intercepts. That means that the two lines are parallel. So, there is not point of intersection from which to compare the x and y values.

Answer 4

@katiek3455654 Look at the yellow/gold line and the pink one.

Can you determine what the x-coordinate of the intersection of those two lines is? Is it greater than one?

Answer 5

before i answer that is the answer c?

Answer 6

Let me look. Do you know which colors the lines are? If not, I'll look.

Answer 7

pink blue green and yellow

Answer 8

These two for c) y = 3x + 2 and y = -1/4 x + 1
are pink and green. They intersect to the left of (0,0) so the x-coordinate of the intersection is not greater than one. So far, options A and C are out. That leaves a choice between B and D.

Answer 9

The colors for the lines of option b are ... lemme see.

Answer 10

Pink and blue. They intersect in the second quadrant where x is negative.

So, which option is left for the answer? @katiek3455654

Answer 11

The pair of lines that intersect in the first quadrant. The pink and the yellow - they are option __?__

Answer 12

b?

Answer 13

These two.

Answer 14

That x has value greater than one.

Answer 15

Not b, not c.

Answer 16

d?

Answer 17

Yes. The x-value of the intersection of the lines on option D is 16/13 which is greater than 1. Final Answer: D

Answer 18

thank you so much!
