How do you graph the equation y = -2x - 1 ?

**Slope-intercept form is y = mx + b**

m is the slope

b is the y-intercept

m is the slope

b is the y-intercept

**rise vertical change**

------ = Slope = ----------------------------

run horizontal change

------ = Slope = ----------------------------

run horizontal change

For y = -2x - 1

- put a point at -1 on the y-axis

- from there, since the slope is -2/1, move down 2 and to the right 1 and put another point

- then, draw a line through the two points
