timofeeve [1]

Answer:

5y-4x= -7 :

Slope = \frac{1.600}{2.000} = 0.800

<em>x </em>- <em>intercept =  </em>\frac{7}{4} = 1.75000

<em>y - intercept =  - </em>\frac{7}{5} =  -1.40000  <------both of these numbers a negative

----------------------------------------------

2y+4y = 14 :

<em>y = </em>\frac{7}{3} = 2.333

----------------------------------------------
