Substitution
y = 3x + 1
y = 6x + 10
x = -3 , y = -8
4x + 9y = 29
6x - 9y = 21
x = 5, y = 1
x - 9 = 24
x = 33
What is the number in front of a pronumeral called?
The Coefficient
y = -2x + 13
y = 4x - 11
x = 4, y = 5
2x - 2y = -18
5x + 2y = -24
x = -6, y = 3
2x + 13 = 29
x = 8
What is the name of the plane on which we plot coordinates?
The Cartesian Plane
4x + 2y = -20
y = x - 4
x = -2, y = -6
8x - 5y = 2
8x + 7y = -22
x = -1, y = -2
17 - 4x = 41
x = -6
What is the smallest prime number?
2
5x - y = 21
y = -7x + 15
x = 3, y = -6
6x - 4y = -8
-9x - 4y = -8
x = 0, y = 2
(x+2)/3 = 1.5 (correct to 2 d.p.)
x = 2.5
What tool is draw a perfect circle?
A Compass
y = -8x - 3
8x + 4y = 12
x = -1, y = 5
4x - 5y = 7
-8x + 5y = 1
x = -2, y = -3
2x - 3 = 4x + 12 (correct to 2 d.p.)
x = -7.5
