If, n(A) 85. n(B) = 110, n(B - A)
50. Find
(a)
n(ANB)
(b) n(AUB)
(c) n(A - B)

Cathy did that number...

It is important because sometimes ur dna needs to multiply

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!
