is useless now i get no help in hw like someone pls help

Plug the point (-1,20) into the equation and see if it holds true.

20<1/2(-1-5)^2+2
20<1/2(-6)^2+2
20<1/2(36)+2
20<18+2
20<20
So it’s true. I left the equals sign out because I couldn’t do it on my phone. The symbol in the question is less than or equal to and it is equal so yes

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!
