➷ Find the total number of marbles (this will be the denominator):

4 + 16 + 5 + 16 + 10 = 51

Probability of pulling out red marble:

4/51

Probability of pulling out a green marble:

10/51

Add these two probabilities together:

14/51 <== the 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!
