When graphing, what do you do after you graph your y-intercept?

• Find slope and start with your run(left or right) then to rise (up or down)

• Find slope and start with your rise (up or down) then to run (left or right)

• Draw a vertical line

• Draw a horizontal line

Which could be the graph of the equation y = 1/3x - 2?

Graph the function

f(x)=3x-5

(remember slope intercept form f(x)=ax+b where a is slope, b is y-intercept) Start by plotting the y-intercept, then count the slope to the next point
