y = 2x - 3

What’s this?

y = 2x - 3 It’s a Linear Equation!

y = 2x - 3 I wonder what form it’s in!

y = 2x - 3 It’s in something called slope intercept form.

y = 2x - 3 It’s in something called slope intercept form. What’s the formula?

y = 2x - 3 The Slope Intercept formula is: y = mx + b

y = 2x - 3 The Slope Intercept formula is: y = mx + b m = the slope of a line

y = 2x - 3 The Slope Intercept formula is: y = mx + b m = the slope of a line

y = 2x - 3 The Slope Intercept formula is: y = mx + b m = the slope of a line B is where the line passes through the y axis

y = 2x - 3 The Slope Intercept formula is: y = mx + b m = the slope of a line B is when the line passes through the y axis

y = 2x - 3 You know what b is. Now you can put the y - intercept on your graph.

y = 2x - 3 The y - intercept is - 3.

y = 2x - 3 What’s next?

y = 2x - 3 Now you have to to look at m which in this case is equal to 2.

y = 2x - 3 Remember. The slope is the rise over fun.

y = 2x - 3 Now you go up two and over one. (2/1)

y = 2x - 3 Now you go up two points and over one.

y = 2x - 3 Now connect the dots with a line. Don’t forget to add arrows at the end of the line to show that it is continuous!

That’s how to graph a Linear Equation!
