Question 2

Which statement is true of this system of equations?

Revolt · Accepted Answer

The second equation converted to slope-intercept form is .

Question 3

What is the solution to the system? (0, 4)(0, –1)✔ (3, –2)(2, –1)

Revolt · Accepted Answer

✔ (3, –2)

Question 4

Verify the solution. Which true statement appears in your check?

Revolt · Accepted Answer

–2 = –2

Question 5

She determined that the solution is (–3, –3). Is she correct? If not, explain why.

Revolt · Accepted Answer

No. She used the wrong slopes when graphing the equations.

Question 6

Question 7

The solution to the system is (–5, –4)✔ (–2, –1)(1, 6)(5, 7).

Revolt · Accepted Answer

✔ (–2, –1)

Question 8

The blue and orange lines represent a system. Use the sliders to manipulate the orange line to determine which equations would create a system that has no solution. Check all that apply. Hint: Convert to slope-intercept form.

Revolt · Accepted Answer

2x + y = –5; –2x = y; 2x = 4 – y

Question 9

y = 7x + 2y = 3x + 5 y – 2 = 4x3y = –9x – 6

Revolt · Accepted Answer

y = 7x + 2; Answer image: //media.edgenuity.com/EVresources/3108-06-03-20-10-task/mr001-1.jpg; y – 2 = 4x
