There is 15 boys in total. 10 of them like fishing.
Therefore, 10/15 boys like fishing.
10/15 = 0.66 = 66.6%

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!
