3x+y = 4 y = -3x+4 Perpendicular slope: 1/3
y = 3x + 1 is a linear equation - it is the equation for a graph of a straight line that crosses the y axis at 1 and the x axis at -1/3, and has a gradient (slope) of 3.
one is y=3x+3 so is y=3x+5
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
(a) y = -3x + 1
y = 3X - 1
y = 3x + 1
y = 3x + 1 y = 3x + 2 y = 3x + 3 y = 3x
1
It is: 1
y=3x+4 -3x+y=4 x=-1/3
You notice the first two items, 3bx + 3x factorizes into 3x(b+1). And the last two, by +y factorize into y(b+1) . So (b+1) is a common factor, so you can factorize these two into (b+1)(3x+y)
y = 3x + 1 y = 3(1) + 1 y = 3 + 1 Y = 4
y = 3x + 21x2 = 3x(1 + 7x)
x =1, y=1
y = 1/3x+4
you mean: y= -3x+1 y+x=-3+1 solve -3+1= -2 y+x = -2
