Answer: plug them in a graphing calculator and you'll automatically get ur answer! Or use y = mx + b method and b would be your y-int (0,b)! mx is example: 2/1 or 2/4! Top number counts up if the mx is positive, if mx is negative it goes down! The bottom number fraction count how far it goes to the right side! mx is constant so it will keep going forever!
3) 2 - 8x + 3x When x = 5
4) 4 - 2x + 5x when x= 4
5) z divided 2 - 4z + 3(z-3) when z =8
GEMDAS!
1:
3 - 7 x 5 + 2 x 4
3 - 35 + 2 x 4
3 - 35 + 8
3 - 27
-24
2:
7 - 2 x 5 + 9 x 3
7 - 10 + 9 x 3
7 - 10 + 27
7 + 17
24
3:
2 - 8x + 3x When x = 5
2 - 8(5) + 3(5)
2 - 40 + 15
2 - 25
-23
4:
4 - 2x + 5x when x= 4
4 - 2(4) + 5(4)
4 - 8 + 20
4 + 12
16
5:
z ÷ 2 - 4z + 3(z - 3) when z = 8
8 ÷ 2 - 4(8) + 3(8 - 3)
8 ÷ 2 - 32 + 24 - 9
4 - 32 + 24 - 9
4 - 8 - 9
