Answer:
x = 117°, 297°
Step-by-step explanation:
Subtract 1 from both sides of the equation and you have ...
tan(x) = -2
Then the arctangent function tells you ...
x = arctan(-2) ≈ 116.5651°, 296.5651°
x ≈ 117° or 297°
X = -6 + y...so we sub in -6 + y for x in the other equation
x - 3y = 28
-6 + y - 3y = 28
-2y - 6 = 28
-2y = 28 + 6
-2y = 34
y = -34/2
y = - 17
x = -6 + y
x = -6 - 17
x = - 23
solution is (-23,-17)
Coefficient is a number that has a letter next to it. None of have it

Answer: slope = 1/3</h3>
===================================================
Work Shown:
Use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (0 - (-3))/(9 - 0)
m = (0 + 3)/(9 - 0)
m = 3/9
m = 1/3
----------------
Basically we subtract the y coordinates, and do the same for the x coordinates as well (subtract in the same order). Afterward, divide the two results. Reduce the fraction as much as possible.
A slope of 1/3 means we move up 1 unit each time we move to the right 3 units.
The slope being positive means the line goes uphill as you read from left to right.
