4x-2y = 9 -2y = -4x+9 y = 2x-4.5 in slope intercept form
9
y+6=4x-3 y=4x-9 This is the slope intercept form: y=mx+b m (slope) = 4
x= -11
3+4x=2y-9 Convert to standard form: 2y = 4x+12 or y = 2x+6 The slope, then, is the coefficient of x ie 2.
slope = -4 for y=mx+c, slope=m, y intercept=c
If: -4x+2y = 9 Then: 2y = 4x+9 Divide all terms by 2: y = 2x+4.5 which is now in slope intercept form
y = (4x+9)/(2x+3)2xy+3y = 4x+93y-9 = 4x-2xy3y-9 = x(2-2y)x = (3y-9)/(2-2y)So, inverse function is 3x minus 9 divided by 2 minus 27.
3x-4y = 9 -4y = -3x+9 y = 3/4x-9/4 The equation parallel to this can be y = 3/4x+9/4 because the slope or gradient is the same but the y intercept is different.
9
minus 4 plus 9 = 5, so 5x
Let 6x - 2x - 9 = a, where a is an arbitrary constant. Then 4x - 9 = a 4x = a+9 x = (a+9)/4
