5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
The answer is - not are - (-6, 9).
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
(0, -3)
It is: y = 2x-3
(2, 1)
No but y = -1/2x+3 is perpendicular to y = 2x+6
(3, 1)
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
The answer is - not are - (-6, 9).
x+y=3 y=3-2x so x+3-2x=3 so x=0 0+y=3 so y=3
2x plus y = -3 (subtract 2x from both sides) y = -2x - 3 slope = -2 y-intercept = -3
x= (-1/2)y-2.5
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
Y=2xx+y=3x+(2x)=33x=3x=1y=2x y=2*1y=2
