Answer:

(d) y = -5/2x -3

Step-by-step explanation:

All of the offered choices are in slope-intercept form, so it makes sense to put the given equation in that form. Solving for y, we get ...

5x +2y = -4

2y = -5x -4 . . . . . subtract 5x

y = -5/2x -2 . . . . . divide by 2

The system of equations will have <em>no solution</em> if the equations are "inconsistent." That will be the case when the slope is the same, but the y-intercepts are different. That means you're looking for an answer of the form ...

y = -5/2x +c . . . . . . where c is not -2

This matches the last choice:

y = -5/2x -3

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 4x + 3y = 12 ( add 4x to both sides )

3y = 4x + 12 ( divide the terms by 3 )

y = $\frac{4}{3}$ x + 4 ← in slope- intercept form

with slope m = $\frac{4}{3}$ and y- intercept c = 4

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

Given

- 5x + 3y = - 9 ( add 5x to both sides )

3y = 5x - 9 ( divide the terms by 3 )

y = $\frac{5}{3}$ x - 3 ← in slope- intercept form

with slope m = $\frac{5}{3}$ and y- intercept c = - 3
