The area at the top of the plate is 63 inches squared
The Most Logical Answer is B
Answer:
the formula: Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
how to find the slope intercept:
- Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
- Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Answer:
(x+y) / 72
Step-by-step explanation:
Kate needs to read 2 books
she's not sure how many pages are in each book.
Let
Number of pages in the first book = x
Number of pages in the second book = y
Total pages of the two books = x + y
Kate's summer vacation = 72 days
she is planning to read the same number of pages each day of her summer vacation.
Number of pages she will need to read each day = (x+y) pages / 72 days
Number of pages she will need to read each day = (x+y) / 72
Answer:
y + 20 = 9(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the lie
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, - 20) and (x₂, y₂ ) = (9, 79)
m = 
= 
= 9
Using (a, b) = (- 2, - 20), then
y - (- 20) = 9(x - (- 2)), that is
y + 20 = 9(x + 2)
