It is a straight line equation whereas 3 is the slope and 2 is the y intercept
Their graphs are.
3x + 2 = Y
2
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
x = -4 and y = 2
y=x-2
y = 3x + 1 y = 3x + 2 y = 3x + 3 y = 3x
(-2, 4)
Y=2xx+y=3x+(2x)=33x=3x=1y=2x y=2*1y=2
x = -3, y = 7
4x - y = 1 3x + y = 13 Simultaneous Equations. Add ; This will eliminate 'y' Hence 7x = 14 x = 2 When x = 2 3(2) + y = 13 6 + y = 13 y = 13 - 6 y = 7 Hence the solution in ( x,y) form is ( 2, 7).
