this week in math 10 we started a new unit on slope and linear functions. i will be showing how to find the slope on a graph.
first you need to know the slope formula
slope= rise/run
rise=y
run= x
so above is the formula on how to find the slope
the reason why y=rise and x=run is because when were looking at it on a graph we would go up or down on y or the top number and to the sides on x or the bottom number.
this is what i will be using as an example
to find the rise you would see how many squares/numbers you need to go up to reach the line
and because this slope is going up it will be positive.
the rise would be one because it only took one to line up with the slope.
now we have our rise we need to figure out our run
to do this we need to figure our how many points it takes to reach the line/slope
for this one it would take 2
now we have our rise and run.
rise=1
run=2
from there we would turn it into a fraction
1/2 would be the slope on this graph, to check if it’s right try using it again until you reach the top.
