Brums [2.3K]

Answer:

  • y = 2x + 3
  • y = -6x
  • y = -x + 2
  • y = 2x - 7

Step-by-step explanation:

<u>Slope-intercept form:</u>

  • y = mx + b

<em>Hint. if we have x = 0, then the y-coordinate is the same as b</em>

<u>Slope</u>

  • m = (y2 - y1)/(x2-x1)

33.

  • m = (9 -(-3))/(3 - (-3)) = 12/6 = 2
  • b = 3 as per table (0, 3)
  • y = 2x + 3

34.

  • m = (0-12)/(0 - (-2)) = -12/2 = -6
  • b = 0, as per table (0, 0)
  • y = -6x

35.

  • m = (2 - (-2))/(0 - 4) = 4/-4 = -1
  • b = 2, as per table (0, 2)
  • y = -x + 2

36.

  • m = (-5 - (-1))/ (1 -3) = -4/-2 = 2

Using point (3, -1)

  • -1 = 2*3 + b
  • b= -1 - 6= - 7
  • y = 2x - 7

Helppp meee plssss
Volgvan

Answer:

  • Cost of fish = Php. 60, amount of fish = x kg
  • Cost of chicken = Php. 120, amount of chicken = y kg
  • Budget = at most Php. 1200

a) <u>Required inequality (not a system as only one condition is given):</u>

  • 60x + 120y ≤ 1200

<u>Simplified:</u>

  • x + 2y ≤ 20
  • <em>The graph is attached</em>

b) <u>Verify ordered pair (10, 7):</u>

  • 10 + 2*7 ≤ 20
  • 24 ≤ 20

False inequality, so this pair is out of solution set
