Calculate the Slope
(2, 1) and (3, 2)
What does "m" represent?
Slope
What type of slope does a line have that is going down from left to right?
Negative slope
y = 4
x = y + 3
(7, 4)
Solve for x: 12x + 14 = -22
x = -3
(2, 5) and (4, 6)
m = 1/2
What does "b" represent?
What type of slope does a line have that is going up from left to right?
Positive slope
x = 6
y = 5x - 12
(6, 18)
A right triangle has a leg that is 24 feet and a hypotenuse that is 26 feet. How long is the missing side length?
10 feet
(-3, 2) and (4, -1)
m = -3/7
What is slope-intercept form?
y = mx + b
What type of slope does a line have that is going straight across from left to right?
0
y = 3x - 2
y = -2x + 8
(2, 4)
What is the definition of a "function"?
For every input, there is one output.
(-2, -4) and (8, 2)
m = 3/5
Write in slope-intercept form: 2x + y = 8
y = -2x + 8
What type of slope does a line have that is going straight up and down?
Undefined
y = 2x + 9
y = - x + 6
(-1, 7)
Solve for x: 6x + 12 = 6x + 8
No solution
(2, 5) and (2, -3)
Write in slope-intercept form: -4x + 3y = 12
y = 4/3x + 4
When graphing systems of equations, WHERE on the graph is the solution to the system of equations?
Where the lines intersect.
y = 2x - 4
14x - 4y = 10
(-1, -6)
