Answer 1

The slope is:

⇨ -5

Work/explanation:

This equation is almost in perfect slope intercept. Let's rearrange it just a little.

`\sf{5x+y=-9}`

`\sf{y=-5x-9}`

Now, parallel lines have equal slopes. This means that whatever the slope of line A is, the slope of line B will be the same, if lines A and B are parallel.

The slope of
`\sf{y=-5x-9}` is -5.

So the slope of the line parallel to it is -5.

Answer 2

Using the slope-intercept form, the slope is 5 . All lines that are parallel to y=5x−9 y = 5 x - 9 have the same slope of 5 .
