(geometry pls) what is the approximate measure of angle f? use the law of sines to find the answer.
11.5°
44.4°
68.0°
81.9°

You can just use sine.

Sin(F) = opposite/hypotenuse = 28/40.

F = (28/40)

Plug into your calculator.

44.4

If you use sine
Sin(F)=opp/hyp =28/40
F = Sin - 1(28/40)
Plug it in which equals 
44.4

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!
