Write the slope intercept form equation of the line that goes through the points given in the table.

Write the slope intercept form equation of the line passing through the points in the given table.

Slope can by found from a table by... (select all that apply)

• Finding the "change in y over change in x"

• Finding the "change in x over change in y"

• Picking 2 points and using the slope formula

• Plotting the points on a graph and doing "rise over run"

• Looking at where the line crosses the y-axis

• Calculating "rise over run"

• Calculating "run over rise"

What makes a graphed relationship proportional?

• It is linear

• The line is only in quadrant 1
