Answer:
The slope of the line given by the equation -3x=30-5y is  .
.
Step-by-step explanation:
-3x=30-5y
Move the -3x to the right side of the equal sign and the -5y to the left.
5y=30+3x
By switching them to opposite sides, their sign changes from - to +.
Then, divide both sides by 5 in order to isolate the y.

You get:
<em>y= </em> <em />
<em />
According to y=mx+b, mx refers to the slope.
In this case, the slope would be  .
