Answer: -7
Step-by-step explanation:
The equation is in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept
Therefore, the m value is -7 and it is the slope

Answer:
(-2, 3)
Step-by-step explanation:
Given the system of equations:
-3x + 2y = 12
x = 2y - 8
You can 'substitute' the expression '2y - 8' for the value of 'x' in the first equation and solve for 'y':
-3(2y - 8) + 2y = 12
Distribute: -6y + 24 + 2y = 12
Combine like terms: -4y + 24 = 12
Subtract 24 from both sides: -4y + 24 - 24 = 12 - 24 or -4y = -12
Divide both sides by -4: -4y/-4 = -12/-4 or y = 3
Use y = 3 to solve for 'x':
x = 2(3) - 8 or 6 - 8
x = -2
(-2, 3)
−1/3⋅(8 1/7)
change 8 1/7 to an improper fraction
8 1/7 = (7*8 +1)/7 = 57/7
-1/3 * 57/7
-57/21
21 goes into 57 2 times with 15 left over
-2 15/21
divide top and bottom of the fraction by 3
-2 5/7
Choice B
Y-axis, x-axis, y-axis, x-axis
