Can someone help me with this one please

Im not sure what it means by the entire triangular region so ill tell you that the highlighted right triangle's area is 60, and the area for both triangles is 120. semicircle area is 201.06. total area for entire shape is 321.06.

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!
