Answer:
x = 71°
Option B is correct answer.
Step-by-step explanation:
We need to find for what value of x is , where 0°< x < 90°?
Solving:
So, we get x = 71°
Option B is correct answer.
Based on the equation, the coordinate point is (-4, 2). It is -4 because in the original equation, it's 
, but because it's positive, that must mean it was originally a negative. Why? Because a negative times an negative equals a positive.
Now, let's convert this to Slope-Intercept Form.
y - 2 = 2/3(x + 4)
y - 2 = 2/3x + 8/3
Add 2 to both sides.
y = 2/3x + 14/3
The slope of the line is 2/3 and the original point was (-4, 2).
Now, let's convert this to Slope-Intercept Form.
y - 2 = 2/3(x + 4)
y - 2 = 2/3x + 8/3
Add 2 to both sides.
y = 2/3x + 14/3
The slope of the line is 2/3 and the original point was (-4, 2).
