What she has to do is divide her amount of sunflower seeds into the number of packages that she needs: so 1/2 pounds into 8:

-if we divide a fraction, we can multiply the denominator by the number we want to divide it by.
This is the correct answer, each packet will weight 1/15 of a pound, that is one ounce
The slope is 3 because you need to use the slope-intercept form y=mx+b to find the slope of m
I believe it is the first 1
x isn't a linear equation, it's just a variable or an expression or a letter of the alphabet.
x = 0 is a linear equation and is a line in the Cartesian plane. In fact, it's the y axis itself.
So every point on the line x=0 is a y intercept.
There is no "the" y intercept, no unique y intercept.
