Slide 3

Objectives You will be able to write and graph linear equations in slope-intercept form.

Slide 4

Key Idea: SLOPE-INTERCEPT FORM The slope-intercept form of a linear equation is y=mx+b Where m is __________, and b is the ___ ____________.

Slide 5

Example Write an equation of a line in slope intercept form with the given slope and y- intercept. Then graph the equation. Slope: and y intercept: 3

Slide 6

Example Rewrite 3x-4y=12 in slope-intercept form and graph:

Slide 7

Example Rewrite 4 + 4y = x in slope intercept form and graph:

Slide 8

Graph y=-2

Slide 9

Example Which equation is right? Y= -2x +2 Y= 1/2x +2 Y= 2x + 2 Y=-1/2x+2 Y=-1/2x -2
