Answer:
y = 4/5 x - 2 1/5
Step-by-step explanation:
1. Find the slope:
1 - 5/ 4 - 9 = 4/5 = m
2. Find b by plugging in the m and one of the points given into y = mx + b
1 = 4/5 ( 4) + b
1 = 16/5 + b
-2 1/5 = b
3. Write the equation using the m and the b you just found
y = 4/5 x - 2 1/5

Answer:
$6
Step-by-step explanation:
In order to find the amount of the tip that T.J. and Lindsey will leave for their waiter, you have to multiply the lunch cost for the percentage they want to leave as a tip for their waiter:
Lunch cost=$30
Percentage they want to leave as a tip= 20%
$30*20%=$6
According to this, the answer is that the amount of the tip is $6.
Answer:
32%
Step-by-step explanation:
Area of rectangle ABCD = 20 * 30 = 600 Sq cm
After increasing the length and width of the rectangle by 20% and 10% respectively.
New length = 30 + 20% of 30 = 30 + 6 = 36 cm
New width = 20 + 10% of 20 = 20 + 2 = 22 cm
Area of new rectangle = 36*22 = 792 Sq cm
Increase in area = 792 - 600 = 192 Sq cm
Percentage increase in area
= (192/600) *100
= 32%
