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 />
According to y=mx+b, mx refers to the slope.
In this case, the slope would be
.
To find the inverse of a relation, we switch the x and y values in each point.
So the inverse would be {(4, -3), (0, -1), (0, 6).
Well, all we have to do to figure out if Ms. Lee’s offer is reasonable is multiply the unit price ($18) by 7
18 x 7 = 126
Since she offered $146, she could actually purchase 8 pennants for $144
Therefore, her answer wouldn’t be reasonable
Hope this helps you
