Transcript of Slope!!!

All about slope!! These are all slopes except 1! when you have to solve your slope
you have to use --Rise and Run!! This is not a slope!! Positive Slope- measurement when a line's right end is higher than its left end Negative Slope- measurement when a line's left end is higher that its right end
Zero Slope- measurement of a horizontal line, when there is no change in y-points #1 step
SlopeFormula- y = mx + b
y represents the y-coordinate;
x represents the
x-coordinate m
represents the slope of the line!! #2 step
Slope Calculation- (y2 - y1) / (x2 - x1)
Horizontal lines have a slope of zero because change in y is equal to zero (m = 0)
#4 step
Vertical lines have an undefined slope because change in x is equal to zero
#5 step
A rising 45° line has a slope equal to 1; a falling 45° line has a slope equal to -1
#6 step
If (2, 4) is a point on the line, what is the slope of function y + 2 = mx?
step #7
Put function into form of slope formula
y + 2 = mx --> y = mx - 2
final step
Solve for m
y = mx - 2 --> 4 = (m)(2) - 2 --> 2m = 6 --> m = 3 negitive slope positive slope Thank you for watching my prezi!!!! By:
