Me y=-2x+2 y=2x+2 y= -1/2x+2 y= 1/2x+2

y = mx + b

"m" is the slope, "b" is the y-intercept [the y value when x = 0, so (0,#)]

You can find the slope by using the slope formula and plugging in 2 points:

Or you can use this:

Rise is the number of units you go up(+) or down(-)

Run is the number of units you go to the right.

If you look at the graph, from each point you go down 2 units, and to the right 1 unit, So you slope is -2/1 or -2. When x = 0, the y value is 2, so your y-intercept is 2.

y = -2x + 2   The first choice is your answer

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6

they r 125, and 216

so the sequence goes 1,8,27,64,125,216
