Please help! 15 points to whoever graphs and solves it!
monitta

First you have to get the equation into slope/intercept format: y = mx + b

3y > -3+6x\\\\\frac{3y}{3} >\frac{-3+6x}{3} \\y >\frac{3(-1+2x)}{3} \\y > -1+2x\\\\y>2x-1

So the slope m = 2, and the y-intercept b = -1.

b tells you where the line intersects the y axis. The slope is rise (vertical distance) over run (horizontal distance). I have attached my best attempt at drawing this without graph paper.  The dotted line represents the inequality, and the solution set includes the values above the line which is why it is shaded. Hope this helps!

M is the midpoint of QR<br><br> M = (-2,6)<br> Q= (8,-10)<br> R = ????
Zolol [24]

Answer:

R = (-12, 22)

Step-by-step explanation:

Unfortunately it's not a straight line, so gonna need to put in some extra work. Basically think of it like breaking it into it's horizontal and vertical components then doubling them.

From Q to M you move 10 spaces to the left, so to go from M to R you will go another 10 to the left.  Similarly, you start at -10 for the y value and go up 16 to 6, and you  will need to go up another 16 to get to R.

So for x, 8 -10 = -2 then -2 - 10 = -12, so R's x value is -12

y we do the same thing.  Gonna do it in one step though.  -10 + 16 + 16 = 22

So R is (-12, 22)
