First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6
The answer is 1because a number is multiple by 20 then 200 and multiple by 3 -7=1
(9x^2-4)..........................
The answer I think 174 degrees.
