Use formula: y-y1/x-x1=m(gradient)
so, y=-14x-1
m=-14
y-0/x-2=14/1
y=-14x+28

To compare unit prices, you first have to find the unit prices
for whistles, the unit prices are:
$21.25/25=0.85
36/50=0.72
60/80=0.75
difference between the highest unit price and the lowerest: $0.85-$0.72=$0.13
Kazos: 10/25=0.40
18.5/50=0.37
27.20/80=0.34
so the highest unit price is $0.40
An obtuse angle is an angle with more than 90 degrees and less than 180. so, we can add < 180 and > 90 to the expression, making it the inequality 180 < 3x + 24 > 90. we then solve.
3x + 24 > 90 and 3x + 24 < 180
3x > 66 and 3x < 156
x > 22 and x < 52
so x can be anything more than 22 and less than 52 (it cannot be 52 or more or 22 or less)
hope this helps!
