If y=.1x+3, then .1x = y - 3. Multiply both sides by ten and x = 10y - 30.
If you mean: 2y = -1x-8 then it is y = -1/2x-4
Let y = 3x y' = 3(x)' y' = 3(x1)' y' = 3[1x(1-1)] y' = 3(1x0) y' = 3(1 x 1) y' = 3 In general: y = xn y' nx(n-1)
1+1+x+x+x+y+y=2+3x+2y
y=-1x
y=x y=1x The slope is one.
y = -1x/2 3x + 6y = 0 -3x -3x __________ 6y = 0 - 3x --- -------- 6 6 y= -3x/6 y= -1x/2

In the equation [ y = - 1x + b ], the y-intercept is 'b'.Take the point you know ... (60, 70) ... and plug it into the equation:y = - x + b70 = - 60 + bAdd 60 to each side:130 = bAnd there you have it!The y-intercept is 130 .
