Yesterday’s Homework 1.Any questions? 2.Please pass your homework to the front. Make sure the correct heading is on your paper. Is your NAME on your paper? Make sure the homework is 100% complete. Incomplete work will NOT be accepted.

Slope-Intercept Form (in function form) 10/30/2015 Heading TSWBAT: graph a line using the slope and y-intercept when in slope-intercept form. Students graph a linear equation and compute the x- and y- intercepts (e.g., graph 2x + 6y = 4). They are also able to sketch the region defined by linear inequality (e.g., they sketch the region defined by 2x + 6y < 4).

Slope-Intercept Form Notes y is by itself on the left. What do you notice? x comes first on the right. Find the slope and y-intercept. Ex. Rewrite the Slope-Intercept Formula! Ex. Rewrite the Slope-Intercept Formula! Ex. Now you try.

Notes Find the slope and y-intercept. Ex. Rewrite the Slope-Intercept Formula! Make it look like slope-intercept form! Ex. Rewrite the Slope-Intercept Formula! Make it look like slope-intercept form! Now you try. Ex.

Notes Write in slope-intercept form Ex. Now you try. Ex.

Rules for Graphing by Slope-Intercept Form Notes 2. Find the slope (m) and y-intercept (b). 3. Plot the y-intercept. b = beginning 4. Plot more points by using the slope. m = move 5. Make a line by connecting the dots. 1. Put in slope-intercept form.

Notes Ex. Graph. 2) Find m and b. 3) Plot the y-intercept. 4) Plot more points by using the slope. 5) Make a line by connecting the dots. 1) Put in slope- intercept form. b = beginning m = move
