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
