There are 20 tiles in a bag. of these, 9 are purple, 5 are black and the rest are white. event a= drawing a white tile on the first draw event b= drawing a black tile on the second draw if two tiles are drawn from the bag one after the other not replaced, what is p(b|a) expressed in simplest form? a. 1/4 b. 5/19 c. 3/10 d. 9/20

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!
