First of all, lets get y on its own side of the equation.

This is slope intercept form, y=mx+b, where m is slope.
we can see that m=2, so the slope is 2 or

Answer:
Answer will be 4.
Step-by-step explanation:
Given equation is:
41 = 12 d - 7
or
12 d = 41 + 7
12 d = 48
d = 48/12
d = 4
{<em>q</em>, <em>r</em>, <em>s</em>} consists of 3 elements, so there are 2³ = 8 possible subsets.
• empty set: { }
• every possible singleton set: {<em>q</em>}, {<em>r</em>}, {<em>s</em>}
• every possible pair: {<em>q</em>, <em>r</em>}, {<em>q</em>, <em>s</em>}, {<em>r</em>, <em>s</em>}
• the set itself: {<em>q</em>, <em>r</em>, <em>s</em>}
