Lesson 3: Slope

# Intro to slope

Slope tells us how steep a line is. It's like measuring how quickly a hill goes up or down. We find the slope by seeing how much we go up or down (vertical change) for each step to the right (horizontal change). If a line goes up 2 steps for every 1 step to the right, its slope is 2.

• Without doing any calculations how do you know that one slope has a higher slope than another line?
• You can know if one slope has a higher slope without calculations because the higher the slope the steeper the line. Great question!
• I don't get slope at all; can somebody explain it to me?
• it's really simple, dude.
basically it's just the rise over the run, which means its the amount that goes up, divided by the amount going sideways. think of it this way. when your rising, your going up, so your going up on your graph, but when your running, your going sideways (usually) meaning across your graph. if the line is steeper, you will get a larger slope. if it is not as steep your slope will be smaller
• How do you find slope of a straight horizontal line? my brother said it would be one, but im not sure... Thanks in advance!
• 0 always
• Why can't it be 'increase in horizontal/ increase in vertical' or 'run over rise'?
• It kinda makes no sense as we are measuring the amount of steepness i.e higher the number --> steeper the slope. In your question it is the opposite

• Wow, great poem!
• how do I caculate a slope
• Without doing any calculations how do you know that one slope has a higher slope than another line?
• You just imagine both of them in on place
or look which one has greater angle from same x line
