Answer:
I LOVE POINTS!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
Best Answer:<span> </span><span>I'll make one up and explain how to do it.
Lets say your two points are (2,6) and (-4,7)
To start with you need to use the point-slope formula which is y2-y1/x2-x1
Remember (x,y), Thus we have
7-6/-4-2 = 1/-6; So out slope is -1/6
Now lets use the following equation y = mx+b to solve for b which is the y-intercept. By substitution of either order pair we can solve for b
6 = 2(-1/6)+b; distribute the 2
6 = -2/6+b; add 2/6 to each side to isolate b
6+2/6 = b; put 6 over 1
6/1+2/6 = b; get a common denominator between 6/1 and 2/6 which is 6
6(6/1)+2/6 = b ; distribute
36/6+2/6 = b; add these up
38/6 = b; reduce to lowest terms by dividing by 2 to each
19/3 = b
So our final equation is y = -1/6x+19/3 </span>
Let <em>x</em> be the number of pearls in Chang's collection. Let <em>y</em> be the number of pearls in Cal's collection.<em />
Chang has 3 more than Cal, so <em>x</em> = <em>y</em> + 3.
Adding both collections would be <em /><em>x</em> + <em /><em>y.</em> It's easier to have an expression in one variable, so we will substitute what we had written about Chang in for <em>x</em>.
(<em>y</em> + 3) + <em>y</em> = 2<em>y</em> + 3.
362 because if you multiply 30 by 12 you will get 3 hundred 60 two
