What does x+1/ 2=y+2/ 3=x+y/ 4 equal? what's x and y? (the 2,3,4 are whole numbers next to the dash)

Will mark name all segments skew to bc

The points (1, 7) and (0, 2) fall on a particular line. what is its equation in slope-intercept form?

The discrete random variables x and y take integer values with joint probability distribution given by f (x,y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x,y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
