Answer:
y= -2x + 4
Step-by-step explanation:
-2 - 4 = -6
3 - 0 = 3
-6 ÷ 3 = -2
-2x is the slope.
3 × -2 = -6
-2 - -6 = 4
4 is the y intercept
Answer:
The answer is A.
Step-by-step explanation:
3p + 4c = 40 ⇒ 15p + 20c = 200
5p + 2c = 34 ⇒ 15p + 6c = 102
14c = 98
14 14
c = 7
5p + 2(7) = 34
5p + 14 = 34
- 14 - 14
5p = 20
5 5
p = 4
(p, c) = (4, 7)
