For this case we have that by definition, the equation of a line in the point-slope form is given by:

(y-y_ {0}) = m (x-x_ {0})

Where:

(x_ {0}, y_ {0}): It is a point through which the line passes

m: It's the slope

We have according to the graph, that the line goes through:

(x_ {1}, y_ {1}): (- 2, -1)\\(x_ {2}, y_ {2}) :( 2,1)

We found the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {1 - (- 1)} {2 - (- 2)} = \frac {1 +1} {2 + 2} = \frac {2} {4} = \frac {1} {2}

Thus, the line is of the form:

(y-y_ {0}) = \frac {1} {2} (x-x_ {0})

We substitute a point:

(y-1) = \frac {1} {2} (x-2)

Answer:

(y-1) = \frac {1} {2} (x-2)

Answer:

  • c. 126.27 square feet

Step-by-step explanation:

<u>Area of rhombus is:</u>

  • A = pq/2, where p and q are diagonals

<u>We have:</u>

  • p = 18.3 ft
  • q = 13.8 ft

<u>The area is:</u>

  • A = 18.3*13.8/2 = 126.27 ft²

Correct choice is C

On a particular day, the wind added 4 miles per hour to Alfonso’s rate when he was cycling with the wind and subtracted 4 miles
Greeley [361]

d = r · t ⇒ t = d/r

going

t = 54/(r + 4)

coming

t = 30/(r - 4)

54/(r + 4) = 30/(r - 4) times are equal

54(r - 4) = 30(r + 4) product means/extremes

54r - 216 = 30r + 120 distribute

24r - 216 = 120 subtract 30r from both sides

24r = 336 add 216 to both sides

r = 14 divide both sides by 24

Alfonso bikes at 24 mph.
