If two variables x and y are perfectly positively correlated then in the scatter diagram every point (x, y) lies on

If two variables x and y are perfectly positively correlated then in the scatter diagram every point (x, y) lies o

The point (x, -2/5) lies on the graph of y = 4 - 2x/5. The value of x ischoices:-113

The point of the form (a, a) always lies on:(a) On the line x + y = 0(b) On the line y = x(c) x-axis(d) y-axis

If point  P(x, y) is such that  y  =  x3 − 2x2 − 7x + 5&x  =  2 + √3 then point  P(x, y) is?

(-10,2) is point of y =f(¹/₂x+3)-2,      then point of y==f(-¹/₂x+3)-2 is*(-10,-2)(10,-2)(10,2)(-10,2)
