Finding gradient
The gradient of the equation y = -3x + 5.
What is -3?
Rearrange to the form y = mx + b (so y doesn't have a co-effient)
2y = 6x + 2
y = 3x + 1
Write the equation of the line with a slope of 3 and y-intercept of -2.
What is y= 3x-2?
7x - 6(x - 8) = 39
What is -9?
Free 100 points to whomever selected this.
What is YAY?
The gradient of the equation y = 1/2x + 7.
What is 1/2?
Rearrange to the form y = mx + b (so y doesn't have a co-effient)
4y = 6x + 8
y = 3x/2 + 2
Write the equation of the line with a slope of -1/2 and y-intercept of 1
What is y= -1/2x+1?
-3x - 6(-x - 8) = 15
What is -11?
3 ( a - b) = 3a - 3b
What is Distributive Property?
The gradient of the equation containing the points (0, 5) and (1, 4).
What is -1?
Rearrange to the form y = mx + b
2y + 3 = -10x
y = -5x + 3/2
The slope of the equation is decreasing by 1 and the y-intercept is 6
What is y= -x+6?
3x + 6(-2x +18) = 162
What is -6?
8 * 7 * 6 = 7* 8 * 6
What is the Commutative Property of Multiplication?
The gradient of the line containing the points (1, 3) and (2, 5).
What is 2?
Rearrange to the form y = mx + b
-2y - 6 = x
y = -x/2 - 3
The slope of the equation is decreasing by 1/5 and the y-intercept is -3
What is y= -1/5x-3?
x/5 + 5 = 16
What is 55?
14 + 0 = 14
What is the Identity Property of Addition?
The gradient of the line represented by the equation y = 2x + 4
What is 2?
Rearrange to the form y = mx + b
2y + 5x + 1 = 0
y = -5x/2 -1/2
The slope of the equation rises 2 and runs 3 and passes through the point (0,1)
What is y=2/3x+1?
55 + 7x = -x - 65
What is -15?
(8 * 3) * 2 = 8 * (3 * 2)
What is Associative Property of Addition?
