Slope
What is Slope?
Slope is a value that describes the steepness and direction of a line.
What are equations?
a mathematical statement that shows that two mathematical expressions are equal.
What week of school are we in?
Week 10
What is the simple formula for calculating gradient?
m=rise/run
What is a Y intercept?
The y-intercept is the point where the graph intersects the y-axis.
What makes slope a negative?
A slope is a negative when the graph is going 'down' / when the rise is negative
A way to solve an equation that requires points
Graphing or Algebrecially
Zaraffa's Coffee - Barista
What is the 'better' formula to calculate the gradient
m=(y2-y1)/(x2-x1)
Where is the y intercept in Y=mx+b
Its B
Positive, Negative, Zero and Undefined.
What are linear equations?
Linear equations are an algebraic equation of the form y = mx+b.
What colour is Benji? Extra points: what colour is Shadow?

Shadow - Black and white
What is the gradient of this equation?
y= 3x + 5
m=3
How is the y- intercept calculated?
set X + 0 and solve for y
Whats the slope intercept formula?
Y = mx + b
What are the three forms of linear equations?

Where did Miss Hider go to university?
QUT
What is the gradient of this line?
Rise = 8
Run = 2
m=rise/run = 8/2 = 4
y=4x -6
What makes a slope undefined?
A vertical line.
What are the 4 operations to solve equations?
Addition, Subtraction, Division, Multiplication
What is Miss Hider's biggest pet peeve?
Talking over me.
What is the gradient of this line?
(-5, 7) and (3, 4)
m= (4-7)/(3--5) = -3/8
What is the y-intercept of the line?
(-4, 6) (0, 2)
y-intercept when x=0 therefore y-intercept is 2
