which of the following pairs of numbers have a greatest common factor of 6? 6 and 3 30 an d36 24 and 48 60 and 88 18 and 66 72 and 84

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!
