y - 3 = 4x
What is y = 4x+3
100
2y - 4 = 7x
What is y = 7/2x + 2
100
5y + 3x - 2 = 0
What is y = -3/5x + 2/5
100
2(3 + x) - 4y = 12
What is y = 1/2x + 3/2
100
What does the "m" in "y = mx + b" represent?
What is slope.
200
y + 2 = 5x
What is y = 5x - 2
200
-8 + 4y = 12x
What is y = 3x + 2
200
6x -2y - 12 = 0
What is y = 3x - 6
200
5(x - 2) - 2y = 14
What is y = 5/2x - 12
200
What does the "b" in "y = mx + b" represent?
What is the y-intercept
300
4 + y = x
What is y = x - 4
300
10 - 2y = 18x
What is y = -9x + 5
300
3x - y + 6 = 0
What is y = 3x + 6
300
4y - 4(x - 2) = 32
What is y = x + 6
300
Which do you start with when you graph an equation, the slope or the y-intercept?
What is the y-intercept
400
-7 + y = 8x
What is y = 8x+7
400
6x - y = 6
What is y = 6x - 6
400
5y - 15x + 4 = 0
What is y = 3x - 4/5
400
6(x - 2) + 3(x + 4) = 5y
What is y = 9/5x + 0
400
How do you know if you should go up or down for the slope?
What is positive moves up, negative moves down.
500
5 + y = -5x
What is y = -5x - 5
500
-12y + 12x = 36
What is y= x - 3
500
9 - 3x + 3y = 0
What is y = x - 3
500
5(2x - 5) + 9(2x - 1) = - 2y
What is y = - 14x + 17
500
What happens to the graph when there is only one variable in an equation, such as y = 3, or x = - 4?
What is the graph is a horizontal line (slope = 0) or a vertical line (slope is undefined).
