Slope
What is slope?
A rate of change
What is Y-Intercept?
A point where a ling on a graph hits the y-axis
What is an equation?
A statement where two expressions are equal to each other.
What is system of equations?
A set of situations to equal a common solution
What is the origin?
(0,0)
What is the slope? y = 2x + 5
2
What is the Y-Intercept in slope intercept form?
The b in y = mx + b
What is the answer? 624(562)
350688
When do you use substitution?
When a variable is given to you
Is (0,6) along the y-axis or the x-axis?
Along the y-axis
What is another way people use to find slope?
rise/run
What is the Y-Intercept? y = 8x + 4
4
What is the answer? 3x + 5 = 11
x = 2
When do you use elimination?
When you have to cross out one of the variables to solve.
What does infinite solutions look like on a graph?
Two lines with one on top of the other
What is the formula used for slope?
y2 - y1 / x2 - x1
What does the Y-Intercept show in a word problem?
The starting point/the first point before doing the rate.
What is the answer? 4x + 8 = x - 1
x = -3
What is the answer? 4x+ 2y = 14
3x - 5y = -22
1
What happens when all x points on a graph are 2?
The line is a straight vertical line.
What is the slope? -11 - 8 / 2 - (-3)
-19/5
What is the Y-Intercept? y = 9x
0
What is the answer? 3 (x + 2) - 8x = x + 9
3x + 6 - 8x = x + 9
x = -1/2
What is the answer? -4x + 4y = 20
x + 9y = 19
(-2,10)
What is the function family with the U shaped graph?
Quadratic
