LINEAR FUNCTIONS
run
rise
y = mx + b
m = slope
Slope Method 1: Slope Method 2:
12

xx
yy
y = y-intercept
Method 1: extend the line to the y-axis
Method 2: pick a point on the line (x, y). Substitute into y = mx + b and solve for “b”.
Writing Equations
QUADRATIC FUNCTIONS
y = x2 Parent Function:
y = -x2 Open downward:
y = -x2 + 5 Shift up 5 units:
y = - (x-4)2 + 5 Shift right 4 units:
y = - 0.5(x-4)2 + 5 And Open wider:
