Hey can you me posted picture of question

We are to find P(A' ∩ B).

A' indicates Compliment of A.

Since A and B are independent events, we can use the formula:

P(A' ∩ B) = P(A') x P(B)

P(A') = 1 - P(A) = 1 - 0.4 = 0.6

So,

P(A' ∩ B) = 0.6 x 0.9 = 0.54

So, option A gives the correct answer

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
