Answer:
-2/3x
Step-by-step explanation:
1.) use the slope equation (y2-y1)/(x2-x1)
2.) substitute the points into the equation (2-4)/(2--1)
3.) solve the equation (2-4= -2) / (2--1=3)
4.) the slope is -2/3
Answer:
X is directly proportional to y means the value of x is dependent on the value of y. y may not be dependent on x in this case.
Y is directly proportional to x means the value of y is dependent on the value of x. Same as above, in this case, the value of x may not depend on y.
