Is (2,2) in the solution set of y ≥ 9x - 8?

No (2,2) isn’t a solution

y=2 and x=2
2>_ 9 (2)-8
2>_ 18-8
2>_ 10 this statement is false

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!
