Answer:
y- intercept = - 2.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m = 
= 
= - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5
Answers:
1. No I don't agree with Selena because the area of the rectangle has the exact same area of the square
Step-by-step explanation:
1. square = x
rectangle length = 6 + x
rectangle width = x - 6
the plus 6 and minus 6 cancel each other out and make the same area that the square has.
Im sorry i dont know what the answe to 2 is.
Answer:
$181.44
Step-by-step explanation:
First, you convert the hours worked to minutes <em>(h)×60=(min)</em>.
4 × 60 = 240 4.5 × 60 = 270 7.25 × 60 = 435
Then, you add the minutes worked together.
240 + 270 + 435 = 945
Then, convert the total minutes worked to ours.
945 ÷ 60 = 15.75
Finally, multiply 11.52 (the pay per hour) by 15.75 (the total hours worked)
$11.52 × 15.75h = $181.44
The answer is 8.
57/6 = 8.
