Solve for y.<br><br> 2y - x = <br> 3<br> 4<br> (-y + 1)
Mars2501 [29]

2y-x=3/4(-y+1)first distribute

2y-x=-3/4y+3/4 get the y on one side

2y-x+3/4y=3/4 add 3/4y to both sides

2y+3/4y=3/4+x add x to both sides

11/4y=3/4+x now divide by 11/4 (both sides)

y=3/11+4/11x

y=3+4x/11

choice c is the answer

Which of these points are on a line that has a slope of -3?
Ira Lisetskai [31]
Simple....

using the formula \frac{ y_{1}- y_{2}  }{ x_{1}- x_{2}  } to find slope....

1.)  (9,2)(4,3)

\frac{2-3}{9-4}= -\frac{1}{5} (No)

2.)  (9,2)(3,4)

\frac{2-4}{9-3} = -\frac{2}{6} =- \frac{1}{3} (No)

3.)  (2,9)(3,4)

\frac{9-4}{2-3} = \frac{5}{-1} =-5 (No)

4.)  (2,9)(4,3)

\frac{9-3}{2-4} = \frac{6}{-2} =-3 (YES!)

Thus, your answer.
