what is another point on the line including (2,3) and (3,3) ?
(1,1)
what symbol will you find in every linear equation?
+
slope
A line is another word for its steepness
intercept
A point where a line hits or intercepts the X or Y axis
coordinate plane
A two dimensional representation of space
rise over run
slope (m) = change in y over change in x
what is the value of y when X=5 in the equation y=5x?
y = 25 (5 times 5)
slope intercept form
y= mx + b (m is the slope, b is the Y intercept)
what is the value of y when x=2 in the equation y=2x - 2?
y=2
