Can someone conirm if i'm right or not?

We know that  is the diameter of circle, so . By knowing that central angles have the same degree value as the arcs they form by intercepting the circle, we now know that arc . So, the arc  

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!
