Answer:
a ) x = - 3, y = 5
x = 0, y = 2
x = 5, y = - 3
b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.
Step-by-step explanation:
y = 2 - x
When x = - 3,
= 2 - ( - 3 )
= 2 + 5
y = 7
When x = 0,
= 2 - 0
y = 2
When x = 5,
= 2 - 5
y = - 3

price sold for= 12×150%
= 18
total cost = 18 × 107%
= 19.26
hope this helps you..
y = x² + 4x is an up-opening parabola with x-intercepts 0 and -4.
y ≥ 0 when x≤-4 or x≥0
range: (-∞,-4)∪[0,+∞)
