The rate of change is -2
Step-by-step explanation:
The slope-intercept form of a linear equation is y = m x + b, where
- m is the slope which represents the rate of change
- b is the y-intercept which represent the initial value (value y at x = 0)
∵ y = -2x - 1
- The equation in the slope-intersect form, compare it with
the form above
∴ m = -2
∴ b = -1
∵ m represents the rate of change
∴ The rate of change is -2
∵ b represents y at x = 0
∴ The y-intercept is -1
The rate of change is -2

Answer:
10 units²
Step-by-step explanation:
The shape is a triangle.
The area can be found by multiplying the base (in units) with height (in units) divided by 2.
base = 4 units
height = 5 units
V = pi * r^2 *h
where r is the radius and h is the height of the cylinder
V = pi * 7^2 *4
V = pi* 49*4
pi is approximated by 3.14 or 22/7
V = 22/7 * 49 * 4
V = 616 units ^3
Answer:
$84
Step-by-step explanation:
Find how many miles she traveled by multiplying 80 and 2.
80 × 2 = 160 miles
Next find out how much she gets paid for her mileage by multiply $0.60 and 160.
160 × $0.60 = $96.00
Now find out how much she spent on gas. She gets 40 miles per gallon so solve how many gallons she used by dividing 160 by 40.
160 ÷ 40 = 4 gallons
Then multiply 4 gallons by $3.00
4 × 3 = $12
To find the net rate of pay subtract 96 and 12
$96 - $12 = $84
