## Slope Intercept Form

### Y intercept

• The y-intercept is the point where a line crosses the y axis.

• At this point the value of x is 0.

### Y intercept

• To find the y-intercept, plug 0 in for x in the linear equation and solve for y.

• y=3x-6 (0, -6)

### Slope

• y=3x-6

• To find the slope first find 2 points.

• (2, 0) and (0, -6)

• Then substitute in and solve

• y=mx + b

• m is

• b is the

### Slope Intercept Form

y=3x-6

The slope is

The y intercept is

### 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.

### 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

### You Try

Write the equation of a line with slope -.5 and y-intercept -3

y =

Write the equation of a line with slope 4 and y-intercept -5/2.

y =

### You Try

Identify the slope and y intercept.

y = -5x + 13

Slope:

Y-Intercept:

Identify the slope and y intercept.

y = 1/4x – 2

Slope:

Y-Intercept:

### 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
