Ответ:
1) does k = 1
2) does k = -0.8
3) does k = 1
4) does not
Step-by-step explanation:
1) plot the point and solve the line to get y = x-2 so k = 1
2) plot the point and solve the line to get y = -0.8x so k = -0.8
3) plot the point and solve the line to get y = x + 9 so k = 1
4) plot the points and theres no straight line that goes through the points so it does not show a proportional relationship
Ответ:
75 degrees since it has 2 equal sides.
