Slope Intercept Form

2
Y intercept The y-intercept is the point where a line crosses the y axis. At this point the value of x is 0.

3
Y intercept To find the y-intercept, plug 0 in for x in the linear equation and solve for y. y=3x (0, -6)

4
**Slope y=3x-6 To find the slope first find 2 points. (2, 0) and (0, -6)**

Then substitute in and solve

5
Slope Intercept Form y=mx + b m is b is the

6
Slope Intercept Form y=3x-6 The slope is The y intercept is

7
**Slope Intercept Form To graph y=3x-6 Plot (0, -6) then count slope**

Up 3 right 1 Connect your points to make a line.

8
Writing an Equation Write the equation of the line with slope 3/8 and y-intercept 5. Use slope intercept form: Substitute in for m and b

9
**You Try Write the equation of a line with slope -.5 and y-intercept -3**

10
**You Try Identify the slope and y intercept. y = -5x + 13 Slope:**

11
**Writing an Equation Write the equation of the line with slope 2**

That passes through pt. (1, 4). Use slope intercept form: y = mx + b Substitute in for m Substitute in your points values for x and y Solve for b Use slope intercept form and substitute in b and m

12
You Try Write the equation of a line with slope -3 that passes through pt. (2, 5)
