Help please. can you please help me figure out 4 equations if 4 lines given their graphs.

(green)   y= 7/6x -1

(Black)   y= -2x+4

(Blue)     x= -4

(Red)      x= +4

Step-by-step explanation:

you can enter 2 sets of coordinates per line into a calculator to help you find the equation for each one.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
