Answer:
A. True
Step-by-step explanation:
A generalized slope-intercept equation of a line is of the form:

Where, 'm' is the slope of the line and 'b' is the y-intercept of the line.
The slope is the rate of change of 'y' with respect to changing 'x'. The slope of a line can be positive or negative.
If 'y' increases with 'x', slope is positive. If 'y' decreases with 'x', slope is negative.
In the above equation, the term that is multiplied to 'x' is called the coefficient of 'x'. Here, 'm' is multiplied to 'x'.
Therefore, the coefficient of 'x' in the above equation is 'm'. Thus, from the generalized equation, one can conclude that the coefficient of 'x' in the equation represents the slope of the line.
Hence, the statement is TRUE.
Answer:
a. When vector is added to vector , the resultant is vector such that its magnitude and direction is proportional to the resultant magnitude and direction of the component vectors.
b. ∅ =
(Rx/Ry)
Step-by-step explanation:
Vectors are used to express physical quantities with magnitude and direction. Vectors can be added by the parallelogram method or the triangular method of addition. the magnitude and direction of the resultant vector is usually proportional to the magnitude and direction of the component vectors.
The direction of the angle is found as
tan∅ = Rx/Ry
∅ =
(Rx/Ry)
