Which equation has a slope of -1/2 and a graph that passes through (-3,4)?

  D.  2y +x = 5

Step-by-step explanation:

You can solve for y to find the slope. It will be the x-coefficient. The slopes for the different answer choices are ...

  a) -1/2

  b) -3/4 . . . not suitable

  c) 1/2 . . . not suitable

  d) -1/2

To determine if the line goes through the point, you can substitute for x and y and see if the equation works.

  a) 4 ?= -1/2(-3) +4 . . . . 4 ≠ 5 1/2

  d) 2(4) +(-3) = 5 . . . . . this equation works, so is the correct choice.

The equation with a slope of -1/2 going through (-3, 4) is ...

  2y +x = 5

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
