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 mwhich in thiscase 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!
