Slope from Tables

• the point on the graph where the line crosses the y-axis.

• the value of y when x = 0

​y-intercept

• slope is the ratio of rise over run

• find two points on the graph and make a slope triangle to find the values

slope

the value of y when x = 0

y-intercept

Some text here about the topic of discussion

If the x variable increases by 1 unit, then find the change in y (1st difference) - this will represent the slope

​Finding the slope

​slope is 2

(m = 2)

• If the x variable does not increase by 1, then find the change in the x and the change in the y.

• The ratio of the change in y to the change in x is the slope

​Finding slope

Some text here about the topic of discussion

​slope is 3/2

(m= 3/2)

Determine the y-intercept

Determine the slope

Write in slope-intercept form (y=mx+b)

For a table

y=mx+b

• "b" is the y-intercept

• "m" is the slope

• plot the y-intercept point on the graph

• use the slope to find another point from the y-intercept
