Answer:
-8/9
Step-by-step explanation:
To find the slope of a line using two points, the equation is y2 - y1/x2 - x1.
In this example,
y2 = -2
y1 = 14
x2 = 9
x1 = -9
Plug the points into the equation.
y2 - y1/x2 - x1
-2 - 14/9-(-9)
Next, simplify.
-16/18
-8/9
m = -8/9
Answer:145⁶°
Step-by-step explanation:
You know that the two angles make up a perfectly flat line, which is a 180<span>° angle. So we can create the equation:'
3x + 10 = 12x
Now solve for 'x'. Subtract 3x to both sides:
10 = 9x
Divide 9 to both sides:
x = 10/9
We want to find the smaller angle, so put this value in for 'x' in '3x + 10':
3x + 10
3(10/9) + 10
30/9 + 10
13 1/3</span><span>°</span>
