By the Pythagorean theorem, the missing side is -sqrt7. The definition of sin is side opposite over hypotenuse, so go into Q2 and make an angle and label the side opposite the angle with a 3 and the hypotenuse a 4. The other leg is -sqrt7 cuz x is negative in Q2. The cosine of an angle is the side adjacent over the hypotenuse, so the cos then is -sqrt7/4
The slope of this graph is - 4
Step-by-step explanation:
The slope of a line is , where
- and are two points on the line
- The slope of a horizontal line is zero
- The slope of a vertical line is undefined
∵ The graph is a line
∵ The line passes through points (1 , -2) and (0 , 2)
∴ = 1 and = 0
∴ = -2 and = 2
- Substitute these values in the rule below
∵
∴
∴ m = - 4
The slope of this graph is - 4
